Looking back at the history of Chinese football impacting the World Cup and impacting the Olympic Games, the 2012 London Olympic Games have the least sense of existence! I think there are probably three reasons:
First, because the strength of the team of this Olympic team is poor, the sense of existence itself is insufficient;
Second, because the period of the current National Olympic Team coincided with the extraordinary period of Chinese football, the competent authorities did not have much energy to contact things like warm-up matches;
Third, because of the special format of this Olympic qualifier, the national Olympic team set sail, and the two games ended.

There are too few materials to choose, and there are inherent deficiencies in the beginning of the National Olympic Games
When Liu Chunming established the 1989 national youth team in 2007, there were only more than 300 registered players in the Chinese Super League, the Chinese League A, including the Chinese Second Division, and some of the strength of the Chinese Second Division clubs were indeed too weak, and only half of the players could actually be selected. After the 2009 National Games, there are about 200 players who can still play in the Chinese Super League, Chinese First Division and Chinese Second Division. Don't think about the number of registered players in developed countries in European football, think about the number of registered players in the age group in neighboring Japan and South Korea when it is calculated at 100,000, and this team has lost before it has even started.
There are too few warm-up matches, and the inaction of the FA in special periods has not allowed the team to grow healthily
Fans familiar with the history of Chinese football know what happened to the Chinese Football Association during this time, so this team only had two opportunities to participate in the competition before the Olympic qualifiers, one was the Asian Youth Championship in 2008 and the other was the 2009 Vietnam Four Nations Tournament, and the players lacked experience in the game. Young players around the age of 20 can't get the opportunity to play in the league, and there are no international competitions in the same age group, which also led to the national Olympic team in the qualifiers with Oman, completely faint, do not know how to play!
London 2012 Olympic Games Asian Qualifier Rules
The London Olympics were divided into 3.5 tickets in Asia, and the 35 teams participating in the qualifiers competed in three stages.
Stage 1: 22 teams ranked at the bottom of the round robin, home and away double round robin, the winning 11 teams enter the second stage;
The second stage: the top 13 teams and the first stage winning team 11, a total of 24 teams to fight each other, home and away system, the winning 12 teams enter the third stage;
Stage 3: The 12 teams that qualify in the second stage are divided into 3 groups, home-and-away double round robin, the first place in the group directly qualifies, the second place in the group plays a single round robin competition, and the winning team participates in the play-offs with the representative team of Africa.
The Chinese team ranked 4th and directly participated in the second stage of the competition, and the opponent of the second stage of the competition was Oman.
June 19, 2011 China: Oman 0:1
23 June 2011 Oman: China 0:1
In the third minute of stoppage time, China's Zhou Yun's goal was blown by the referee to be invalid, slow motion showed no offside, and head coach Blazevic was also sent to the stands. At that time, Chinese football was worried about internal and external troubles, and there was almost no right to speak in the Asian arena, and there was no way to be bullied by the West Asian team.
The basic technical difference of the players is the worst team in recent years, and the team does not have the overall core players, which is completely incomparable with the outstanding strength of the core players in the previous national Olympic teams. In the 1989 Olympic age group, only Zhang Linpeng and Wu Xi were able to gain a firm foothold in the national team, and players such as Wang Dalei, Zheng Zheng, Cao Yunding, and Dong Xuesheng were only rotating players.
