After watching the U23 Asian Cup semi-finals Uzbekistan 2-0 Indonesia team, I suddenly had a few questions that I felt incomprehensible: it stands to reason that Shen Yinhao, the referee on duty in this game, has a high level. Similar to Ma Ning, Fu Ming, etc. Their performance in this U23 Asian Cup or the previous Asian Cup was, in the words of the media, "defending the dignity of Chinese football". The question is, in the Chinese Super League, why does their law enforcement always attract such and such controversies? Is it because the level of the Super League is low, and the fans are not able to see and appreciate the law enforcement art of these high-level referees? Another example is Ma Ning, who is known for his "cards" in the Chinese Super League, and it is common for him to get 10 yellow cards or 8 yellow cards or multiple red cards in a game. But when it comes to the Asian Cup or other continental competitions, the frequency of "dealing" is obviously not as high as in the Chinese Super League. Is this the Chinese Super League players playing very roughly, or is Ma Ning's performance different from that of the Chinese Super League and the intercontinental?
