On the night of September 23rd, Chengdu Rongcheng FC returned to Phoenix Hill Stadium for their only home match in September. Although the team suffered a red card in the 28th minute, Chengdu Rongcheng, playing with one less player, managed to beat Shanghai Harbor, the top of the table, 2-1 with high fighting spirit and toughness, achieving a double kill of the "big brother at the top of the table". Meanwhile, due to Wuhan Sanzhen's loss and Beijing Guoan's draw, Chengdu Rongcheng overtook Wuhan Sanzhen and Beijing Guoan, who have 42 points, with 43 points after the win, and have yet to play a game in this round.
It was a night of victory for Chengdu Rongcheng that not only wrote the history of the team, but also witnessed a great story for the club. That night, the club hosted a 100-game ceremony for head coach Xu Zhengyuan in recognition of his 100th game in charge of Chengdu Rongcheng. The matches that Xu Zhengyuan missed due to reasons were not counted in this 100th match, but only the matches that he personally directed.
In the 2021 season, Seo Jung-won joined Chengdu Rongcheng with his Korean coaching team, and in his debut he bluntly said, "We don't want to still be wandering around in China's first division a year from now, and the only way to get a foothold in Chengdu is to go beyond that!" Such a blunt expression impressed the outside world and won him firm support. As expected, Xu Zhengyuan did not disappoint the fans, leading his team to an easy 4-2 victory over Jiangxi Beidamen in the first round of the 2021 China First Division League, a good start to the season.
It is worth mentioning that there is another unforgettable event for many fans in the 2021 season - Seo Jung-won was leading the team to prepare for the third stage of the Central League when he unfortunately received the news that his mother had passed away in South Korea. In his grief, he once considered putting down his work and returning to Korea to deal with his mother's funeral. However, considering the severe situation of the epidemic at that time, Xu Zhengyuan finally chose to stick to his post and continue to lead the team forward.
