In fact, the poor performance of the national football team is not only due to lack of hard work and shame. Willpower, shame, patriotism and so on, these spiritual things are very important for an athlete, but only when the two sides are evenly matched will they play a role. If these spiritual things are the most important, then North Korea should be the strongest team in the world.
An excellent national team must meet the following conditions: a large football population, scientific training and a good professional environment. Unfortunately, these are not available in China. Players who come out in this environment will be useless even if they try hard.
The direct reason why China can't play well in men's soccer is very simple. It's just that the mass base is not good and there are too few people who receive football training systematically. The reserve of young talents is not even as good as that of Vietnam. So it's good that the national team can beat Vietnam now. It's not black, really.
The problem of football in China lies in the system, not in the players. You shouldn't simply blame the players. Because everyone who can become a professional player has made unimaginable efforts and the support and contribution of his family (human and financial resources). Many people may think that men's football players are happy and their wages are not that high, but that is only a small part. Most football players have a hard time.
In fact, under the background of the national system, the development of almost all sports is abnormal. Although football has become professional, it has not completely shaken off the shadow of the national system. There are problems with football, table tennis, weightlifting and gymnastics. But because the results of those projects are so good, no one cares about the problems behind them. The national system is only effective for sports with low professionalism!
