Learn about the first gold cross-country skiing in the Winter Olympics. Do you know the six skiing events clearly？

Skiing is one of the most traditional sports in the Winter Olympics, but there must be many southern friends who "only listen to its name, but don’t see it."
Surprisingly, the origin of skiing is actually in China. For a long time, the origin of SKIing was thought to come from Scandinavia. The English word ski originated from the word SKITH in ancient Norway, and the stone carvings found in Scandinavia show that the locals began to use skis 4,000 years ago in the Stone Age.
Then the exciting time came.
In 2005, a farmer from Xinjiang discovered a cave about skiing rock paintings in Dundebrak, Altay region, Xinjiang-archaeologists speculated that it was the late Paleolithic period of 10000-30000 BC, earlier than the remains in northern Europe.
After continuous discussion and research by multidisciplinary expert teams from Altay and China and foreign experts from the United Nations, and after four major discussion meetings, Altay Declaration and Altay Declaration 2015 were released in 2006 and 2015 respectively.
The Altay Declaration declared that "human skiing originated in Altay, China, Xinjiang", and the release of the Altay Declaration in 2015 marked the international recognition that Altay, Xinjiang was the earliest origin of human skiing.
On August 25th, 2018, Altay also officially became China Xuedu.
There are six kinds of skiing events in this Winter Olympic Games: alpine skiing, cross-country skiing, platform skiing, freestyle skiing, nordic combined skiing and snowboarding. What are the differences?
alpine skiing
Alpine Skiing is a snow racing sport with skis, snowshoes, fixers and ski pole as the main equipment, which slides down from mountain to mountain and along the track set by Qimen.
Alpine skiing will also be a high-frequency word appearing at the opening ceremony of the Winter Olympics.
According to official website information of the Winter Olympics, among all the 91 registered delegations participating in the Winter Olympics, 83 delegations have athletes participating in alpine skiing events, accounting for more than 90%. Among them, there are 66 delegations with 1-3 participants in alpine skiing, which explains why alpine skiing is so "popular" among delegations with fewer participants.
cross-country skiing
Cross-country Skiing is a sport that glides in the mountains and snowfields by means of skiing equipment and using basic techniques such as mountaineering, downhill, turning and sliding.
Cross-country skiing originated in northern Europe, also known as Nordic skiing, and is one of the oldest sports in the world sports history. It was first included in the Winter Olympic Games in 1924.
Cross-country skiing competition routes are divided into uphill, downhill and flat, each accounting for one-third of the whole journey. The highest point of the snow trail does not exceed 1800 meters.
The skis should be marked. According to the regulations, the skis worn by the athletes from the starting point to the finishing point must bear the marks drawn by the judges at the time of departure, because the bottom surface of the skis is coated with snow wax, which is very smooth and helps to slide. Marking is to prevent the athletes from changing skis halfway.
ski jumping
Ski jumping is a kind of snow sports event, which uses skis as a tool and obtains the speed ratio, jumping distance and action posture by its own weight on a specially designed platform.
freestyle skiing
Freestyle Skiing is a kind of snow sports event with skis and ski pole as tools, which is carried out in a special ski resort by completing a series of regulations and optional actions.
It is bred and developed on the basis of alpine skiing, and is composed of three independent events: aerial skills, snow skills and snow ballet.
Nordic combined
Nordic Combined is composed of cross-country skiing and platform skiing. It has been circulated in Norway and Sweden for a long time and has become a traditional Nordic event, also known as Nordic All-around.
snowboard
Snowboarding is a snow sports event that uses a snowboard as a tool to quickly turn and slide down a prescribed hillside route, or take off by landslide in a special "U"-shaped field to complete various difficult movements in the air.

China Football ushered in a historic opportunity： the successful bid will surpass Japan and South Korea.

China Football Association recently announced its bid to host the FIFA World Cup, which has aroused widespread concern and heated discussion in the media. This is not only an important breakthrough in the history of football in China, but also a new milestone in the development of football in China. In recent years, China’s football has performed well in the Asian Cup and other competitions, and the domestic football reform is also constantly advancing, which provides the qualification and confidence for the China Football Association to bid for the World Cup. However, China Football Association faces many challenges. First of all, compared with the football powers such as Europe and America, there is still a gap in the overall strength of football in China, which needs to show enough strength and self-confidence.

Secondly, hosting the World Cup requires large-scale venue construction and infrastructure improvement, and cooperation with local governments and enterprises is needed to jointly promote related work. These challenges are difficult, but I believe that with the efforts of the China Football Association, they can be overcome one by one. Bidding for the World Cup is not only an opportunity for the development of football in China, but also a major test for the sports cause in China. By hosting the World Cup, more people can know about China football and provide more opportunities and support for the future of China football.

As Song Kai said, "The World Cup is a symbol, not only of China football, but also of China sports. Only with the World Cup can we truly become a big country." Therefore, the official decision of China Football Association is worth looking forward to and supporting. The hosting of the World Cup will lay a more solid foundation for China football to enter the world stage, and will also bring new development opportunities for China sports. I believe that in the future, China Football Association will make continuous progress and inject new vitality into the development of football in China.

Let’s look forward to China football shining on the stage of the World Cup! The Chinese Football Association (China Football Association) announced that it would bid for the World Cup, which caused widespread concern. As a gossip reporter, I can’t miss this hot topic. This move is an important step for China football to enter the international stage, and it is also an opportunity to achieve its own breakthrough and progress. Football is an international sport, and the cooperation and exchange between football associations in various countries is very important for the development of this sport. Aware of this, China Football Association is committed to strengthening cooperation with national football associations and promoting the development of football.

Bidding for the World Cup is also part of its in-depth cooperation. The cooperation between Chinese Football Association and International Football Federation will bring great opportunities for China football. The World Cup is one of the biggest events in the history of football, which has attracted the attention of billions of people all over the world. Holding such an event will bring great economic, social and cultural opportunities to China football. This is not only an important step for China football to enter the international stage, but also an opportunity to achieve its own breakthrough and progress. Compared with the past, the present situation of football in China has been greatly improved.

More and more China players have been signed by western clubs, and more and more foreign coaches have come to China to coach. However, compared with the top teams in Europe and South China, there is still a gap in American football. Bidding for the World Cup is an excellent opportunity for China football to show its true strength to the world. In a word, the announcement of China Football Association’s bid to host the World Cup is an important measure, which will promote the development of football in China and bring great opportunities to football in China. This is also an opportunity for China football to go international and achieve its own breakthrough and progress.

Football knowledge： What does offside mean in football match？

Offside is a violation rule in football match, which means that the receiver stands closer to the goal than the second-to-last defender at the moment when the attacker passes the ball and tries to prepare for the attack.

The formulation of offside rules is a perfection of the rules in the development of football matches. In the football match in the 19th century, there is often a picture that the attacking players are all concentrated in the opponent’s restricted area or even in front of the goal, ready to start shooting after receiving the ball. Due to the high concentration of personnel, there is little wonderful cooperation in the football match, and the play is simple and boring.

In order to change this situation, mobilize the players to run actively, and increase the competitiveness and interest of the game, in 1870, the British Football Association formulated the rule of offside. At that time, it was stipulated that there must be at least three defensive players between the catcher and the baseline, otherwise they would be sentenced to offside.

In the following years, the rules of offside were constantly changed and improved. For example, in 1880, the rules of catching goal kick and corner kick were added, and in 1907, the rules of catching the ball in one’s own half were added.

In 1925, international football association board revised the offside rule again, changing the limit of three players to two. This change has greatly promoted the attack and development of football matches.

From the definition of offside, it is not illegal for a player to be offside, but if he is offside and participates in the attack, he will be sentenced to offside violation. Therefore, in the game, some players will choose to stand still after knowing that they are offside, indicating that they are not involved in the attack.

Of course, participating in the attack is not limited to catching the ball. Players who are offside will also be sentenced to offside if they have the following behaviors:

1. Get or touch the ball after passing or touching the ball by the team members, thus interfering with the game.

2. Interfering with the opposing team members, including: ① obviously obstructing the line of sight of the opposing team members, so as to hinder the opposing team members from handling the ball or affect their ability to handle the ball; (2) compete with the opposing team for the ball; (3) there is an obvious attempt to touch the incoming ball close to his position, and this move affects the opposing team members; (4) make obvious actions that affect the ability of the opposing players to handle the ball.

3. Touch the ball after the following situations, so as to gain benefits or interfere with the opposing players: ① The ball bounces or refracts from the goalposts, beams and opposing players; (2) The ball comes from any opposing player who intentionally saves the ball.

It must be noted that the following situations will not be judged offside:

1. Corner kick;

2. Directly connect to goal kick;

3. Throw a foul ball.

Football is a sport in which the feet are the mainstay, the ball is controlled and dominated, and two teams attack and defend each other on the same rectangular court according to certain rules. Football is called "the first sport in the world" because of its strong antagonism, changeable tactics and large number of participants.

The player of football is Cuju in ancient China, which spread to Europe through Arabs, developed into modern football in Britain and spread all over the world. At the second modern Olympic Games held in 1900, football was officially listed as a competition, while the first World Cup was held in Uruguay in 1930. After decades of development, it became the highest honor in football and the most famous and influential football event.

The highest organization of football is the International Football Federation, which was founded in 1904 and headquartered in Zurich, Switzerland. The highest organization in China is the Chinese Football Association, which was established in Beijing on January 3rd, 1955.

The above is an introduction about football.

Never released John Lennon recording sells for $58,300 at Danish auction

A cassette tape recording of an interview with John Lennon and Yoko Ono, including a never-released song, made while they visited Denmark in 1970 sold for 370,000 Danish crowns ($58,300) at an auction in Copenhagen on Tuesday.

The tape, featuring the unreleased song Radio Peace, was recorded on Jan. 5, 1970 by four 16-year-old Danish boys who succeeded in getting an interview with the couple for a school magazine.

Bids for the cassette tape, which was put up for sale along with photographs from the meeting by the former school boys, started at 100,000 crowns. The lot was valued between 200,000 and 300,000 crowns ($31,500-$47,000) before the auction.

It was not immediately known who bought the recording.

During the 33-minute recording, Lennon speaks about the couple’s peace campaign, his frustration with the Beatles’ image and the length of his hair.

The recording also features Lennon and Ono humming along to Christmas songs while dancing around a Christmas tree, Lennon playing the guitar and the couple singing “Give Peace a Chance” and “Radio Peace.”

The up-tempo song, which repeats the words “this is Radio Peace,” refers to a radio station of the same name that Lennon and Ono hoped to establish in Amsterdam, the auction house said.

World’s richest man Elon Musk once slept on an office couch, worked 7 days a week

Tesla and SpaceX CEO Elon Musk recently became the world’s richest man once more, putting Amazon founder Jeff Bezos in second place. With a net worth of $200.7 billion, according to Forbes, Musk today is one of the most recognised and influential people in the tech space, a long, long way from where the Stanford dropout was back in the 90s, when his life had its fair share of struggles.

Unknown to many, Musk’s first project was actually Zip2, a software company that developed an internet-based platform that benefited the newspaper publishing industry by designing online city guides. Founded in 1995, the company was purchased by Compaq Computer in 1999.

During the four years with the company, Musk would share a computer and code everyday at night, seven days a week to keep the website up. In a 2014 commencement speech at the University of Southern California, Musk mentioned that he would sleep on a couch in a small rented office as he couldn’t afford an apartment. He’d also shower at the YMCA. Check out the clip where he talks about his experiences below.

Musk would go on to co-found X.com in 1999, one of the first federally insured online banks. However, the board of directors would replace an “inexperienced” Musk with Intuit CEO Bill Harris by the end of the same year. Musk would eventually return as CEO the following year when X.com would merge with Silicon Valley software company Confinity Inc, which had its own money transfer service in the form of PayPal.

A few more complications later, Musk was ousted by the board again and replaced with Confinity co-founder Peter Thiel. Under Thiel, PayPal became the main focus of the company and when it was acquired by eBay in 2002 for $1.5 billion, Musk received over $100 million, being the largest shareholder with 11.7 per cent.

Musk spoke about getting fired as the CEO in an interview with Max Chafkin, Senior Writer at Inc. Magazine. The interview also touches on how the PayPal-eBay deal eventually made the Tesla Roadster possible. The company’s first car, the 2008 Roadster was the first production electric sports car that Musk describes as “Faster than a Ferrari and more efficient than a Prius”. Check out the video below.
