Although the Chinese men's football team failed to appear in the competition, the Chinese elements in the World Cup are still everywhere. From stadium construction to power supply, from the referee in the stadium to the mascot outside the stadium... Made in China and built in China have provided strong support for the Qatar World Cup. On the evening of November 22 (Beijing time), the Qatar World Cup Group C competition officially started. At the Russell Stadium, which can accommodate 92000 spectators, the Argentina team led by Messi met the Saudi Arabia team. This stadium, built by a Chinese enterprise, has also completed its "debut" in this World Cup. The Russell Stadium, known as the "Golden Bowl", is located 15 kilometers north of Doha, the capital of Qatar. As the main stadium of the Qatar World Cup and the largest stadium, it will not only hold group matches, but also hold such weighty events and activities as semi-finals, finals and closing ceremonies, which will witness the peak moment of the World Cup. In 2016, China Railway Construction International Group won the bid for the construction project of Russell Stadium. It is understood that this is the first time that a Chinese enterprise has undertaken the World Cup stadium project as a general contractor of design and construction, and it is also the largest and most advanced professional football field that Chinese enterprises have undertaken overseas. In order to build this stadium well, more than 1000 Chinese people participated in the construction. Every link from construction equipment to manufacturing technology demonstrates China's plan and wisdom. As the world's largest span double-layer cable net roof single building, the roof cable span of Russell Stadium is 278 meters. The stadium construction adheres to the concept of green environmental protection. The stadium adopts a double curtain wall structure to improve the thermal insulation performance in the hot climate of Qatar. In order to provide a comfortable viewing environment for the players and spectators, there is a separate refrigeration station outside the stadium, and the "breeze" generated by the water-cooled air conditioner enters the stadium through the vents under the seats in the stands... Recently, the World Cup special commemorative banknote launched by the Central Bank of Qatar showed the design of the Russell Stadium on the 22 Qatar Riyal (1 Qatar Riyal is about 2 yuan) banknote. Hassan Alsawadi, Secretary General of the Qatar World Cup Organizing Committee, said that the construction of this complex stadium has proved the technical ability and service level of Chinese enterprises. "For all the people who come to the Russell Stadium to watch the game, they should thank the Chinese engineers and builders."

This is 20 years later, Chinese referees again appeared in the World Cup arena to participate in law enforcement. In May this year, FIFA released the list of referees for the Qatar World Cup.
