In a key match in the 19th round of the Chinese Super League that ended on the evening of July 12, Beijing time, Beijing Guoan lost 1-5 away to the defending champion Shanghai Port, which was also the second largest defeat in the history of the Chinese Super League in the history of the Guoan team.

In this game, although Guoan lacked foreign aid central defender Mamadou, coach Suarez still sent 4 foreign aides to the start, plus the comeback Zhang Xizhe, which is not considered a remnant, but China An lost without temper in the game. Although Lin Liangming took the lead in scoring a goal, he was completely suppressed by the harbor after that, and finally lost 1-5 by conceding 5 goals in a row. If it weren't for the goalpost 4 times to help Han Jiaqi block Harbour's attack, the score might have been even more disparity.

After the fiasco of national security, Ma Dexing couldn't help but criticize national security:Compared with Mount Tai, Guoan is more humiliating. Tarzan was clearly playing with resentment; What do you say about Guoan's ball? Hey, rent out all the young ones and keep the old ones, that's the result! If it weren't for the help of the goalpost and blocking 4, it would be possible for Guoan to reproduce "1 to 9" in this ball! Shame on you!

According to statistics, 1-5 is the second largest defeat in the history of Beijing Guoan Chinese Super League, and the biggest defeat in team history is 0-5 Guangzhou City. And this is also the first time in 7 years that Guoan lost 1-5 away to Harbour again. In May 2017, Harbour also lost to their opponents by the same score in the 11th round of the Chinese Super League. In 7 years, he was humiliated by the harbor twice, and Guoan is indeed sorry for the support and love of Beijing fans all the time.
