Qatar World Cup has crossed the 100-day countdown. As the first World Cup held in the northern hemisphere winter, this international football feast has attracted more and more attention, and will present more "new meanings" to fans.

  Air-conditioned pitches in a class of their own

  This will be an anti-traditional World Cup, because the World Cup is mostly held in June and July, which is the midsummer World Cup that fans are used to.

Although Brazil and South Africa have hosted the World Cup in the local winter, they are both southern hemisphere countries, and they are still in June and July.

The weather in Qatar is very hot, and it is completely impossible to hold the World Cup in June and July. Therefore, the World Cup will be held from November to December, which will directly affect the European club competitions in the New Year.

  Although Qatar will enter winter, the average temperature is still very high.

In order to create a comfortable game environment for players, air-conditioned stadiums came into being, and Qatar World Cup stadiums will use cooling technology.

  The design of the stadium cooling technology was inspired by research on automotive air conditioning.

The cooling of the stadium is like the cooling principle of motor vehicles. Technicians have used similar tools and principles in the cooling technology, and the scale of cooling is undoubtedly larger.

The cooling technology combines thermal insulation with the concept of "directed cooling", meaning that cooling is applied to the area where the body is actually present, making the stadium act like a barrier, containing a "cold bubble".

  "Dumpling skin" mascot is super cute

  The World Cup is coming to Asia again after 20 years. The last time it was jointly hosted by South Korea and Japan, this time it was hosted by the Gulf country Qatar.

After the 100-day countdown to the opening, the Qatar World Cup mascot La'eeb (alias "Raib") will be pre-sold on domestic sales platforms.

  Ra'ib is inspired by the traditional Arabian clothing headdress. His shape is naughty and cute, with a lively expression. The length and width are about 33 cm.

Once the mascot was released, it was loved by many fans and fringe fans. Because of the cute and exquisite dynamic shape, Laib was named "Dumpling Skin" by everyone.

  Ra'ib is an Arabic word for a skilled player.

Ra'ib means eternal youth, from the "mascot universe", and at the same time full of energy.

Raib encouraged everyone to believe in themselves. The World Cup in Qatar is about to start and will bring the joy of football to everyone.

  A company from Hangzhou, China has become the official licensor of the 2022 Qatar World Cup in Greater China. Before that, the company has continuously operated the production and sales of licensed products for the 2014 World Cup in Brazil and the 2018 World Cup in Russia.

  Longest entry list in history

  FIFA officially announced as early as June that the final roster for each team participating in the 2022 World Cup will be expanded from the traditional 23 to a maximum of 26.

In a World Cup group stage match, each team can make up to five substitutions; each team can make up to six substitutions because extra-time may be required for the knockout stage.

The expansion plan of the World Cup should be more beneficial to teams with stronger overall strength.

  The reason why this expansion measure was introduced is that in order to prevent the international players from contracting the new crown pneumonia during the World Cup, FIFA gave the coaches of each team more leeway to line up.

The list of teams participating in the World Cup primaries has been greatly expanded, from a maximum of 35 players to a maximum of 55 players.

  In order to prepare for the World Cup, players on the final squad of each participating team must finish their last game at the club by November 13 at the latest.

During the World Cup, teams can sit on the bench at most 26 people, including a maximum of 15 substitute players, as well as 11 team staff (including at least one team doctor).

  AI-assisted referee

  Modern science and technology are changing with each passing day. Appropriate application of new technologies to football matches to minimize misjudgments and omissions is a boon for fans and football.

The Qatar World Cup will officially use the semi-automatic offside penalty technology for the first time. The technology will use artificial intelligence to assist the referee and linesman to make more accurate offside penalties and minimize the occurrence of offside misjudgments.

  The AI ​​technology will use 12 dedicated cameras to track each player's 29 data points, including the limbs and torso involved in offside decisions, to calculate their exact position on the pitch.

  This technology also requires the tacit cooperation of the game ball, and an inertial measurement unit sensor will be placed in each game ball.

Located in the center of the ball, the sensor sends data to the VAR operating room at a rate of 500 times per second, helping referees accurately detect whether a player is offside on the field.

  'Journey' flies fastest with a ball

  "The 'journey' we present to you is the official match ball of the 2022 World Cup," FIFA wrote in a statement recently.

  The Qatar World Cup match ball "Journey" will be the fastest flying football in the previous World Cup, and it is also Adidas' 14th consecutive football specially made for the World Cup.

At the World Cup in Qatar, fans can expect that the fastest flying football can make goals faster and more, which may be a boon for free-kick experts such as Ronaldo, Messi, and Neymar, and it may also become a goalkeeper. nightmare.

  In addition to the extremely fast speed of the ball, the "journey" of the World Cup ball has other characteristics: for example, the surface of the football is composed of 20 pieces of textured PU skin, which improves the movement stability of the ball; the center design of the ball can provide speed for fast-paced action , accuracy, motion consistency and aerial stability support.

  Unprecedented ease of transition

  Paris Saint-Germain received capital from the Qatar National Fund. In recent years, the transfer market has turned upside down. Fans have already experienced the powerful strength of oil capital.

Hosting the World Cup in Qatar, a country full of pride, will naturally cost a lot.

In order to prepare for the 2022 World Cup, Qatar has a budget of about $220 billion, far exceeding the record $14 billion invested in the World Cup in Russia four years ago, making it the most expensive World Cup in history.

  Of the total budget, about $10 billion will be used for the construction of new stadiums needed for the World Cup, while the remaining $210 billion is not fully used for the World Cup, which is a long-term investment in Qatar's 2030 plan and will be used locally. Build an innovation center with hotels, underground transportation, stadiums and airports that will remain in use long after the World Cup is over.

  Another point is that the Qatar World Cup team does not have to travel long distances from one venue to another in order to participate in the next game, which is very different from the previous World Cup in Russia, Brazil and South Africa.

All 8 World Cup stadiums in Qatar are within an hour's drive, making it very convenient.
