At present, there are three buildings: Shanghai Hongkou, Tianjin TEDA and Chengdu Longquan. It is said that Nanchang and Guangzhou will be built. ? Shanghai hongkou football stadium is a multi-functional comprehensive stadium with professional football field as the main body, and it is the first professional football field in China and even in Asia. With a total construction area of 72,900 square meters, there are 35,000 audience seats and 47 boxes. The use of heating and strong drainage facilities for football turf is the first case in China. The stadium not only has the function of holding high-level international and domestic football matches, but also has leisure and entertainment facilities such as table tennis room, gym, roller skating room and rock climbing with fitness function to provide fitness and leisure activities for the general public. ? Tianjin TEDA Football Stadium covers an area of 75,000 square meters with a total investment of 530 million yuan. After two years of construction, it was completed and put into use in May 2004. It is the first stadium in China designed and built according to international standards, and can host all international A-level football matches such as the World Cup and the Olympic Games. This is the only professional football field wholly owned by the club in China. The football field has 38,000 seats, 70% of which are under the special-shaped ceiling, and there are 37 VIP box seats. The home team and the visiting team have separate lounges, changing rooms, shower rooms and massage rooms. Players, coaches and referees can enter and leave the venue through separate safe passages. The VIP box is equipped with kitchen, bathroom and game playing system, and the windows are equipped with explosion-proof glass, which can be closed or opened as required. ? Sichuan International Football Stadium is located in Longquanyi District, Chengdu, covering an area of 80 mu, with a total construction area of 39,428 square meters and a seating capacity of 30,800 spectators. At the top of the east and west second-floor stands, there is a white ceiling, just like a huge white umbrella covering the top of the head, which is both sunshade and shelter from rain. It is reported that the cost of these two "white umbrellas" alone is as high as more than 50 million yuan. Sitting in the top row of Sichuan International Professional Football Stadium will broaden the horizons of fans. Because the straight line distance from the stadium lawn is only 22 meters, which is closer than the distance from the first row of stands to the sideline of the general comprehensive stadium, it feels like the Premier League stadium that everyone sees on TV, so fans and friends don't have to worry about "not seeing clearly" at all.
