As referees, their duty is to maintain the continuity of the game, control the actions and words of the players and ensure the normal progress of the game. As for Guo's behavior, he shouted come on after hitting a three-pointer, which is controversial in itself. Under normal circumstances, it is understandable to cheer up, but it is not allowed to spit incense words. The referee defined it as provocative behavior, so he gave him a technical foul to calm him down. There is no right or wrong in this way, only.
As a party, he thought he was just cheering normally and didn't do anything drastic, but the referee gave him a technical foul, which he didn't recognize, so he kept talking and even wanted to argue with the referee, but fortunately his teammates caught him.
Indeed, with the progress of CBA league, the controversy of referees is getting bigger and bigger, and this Guo incident has pushed the referee's penalty scale to a new height. After all, CBA represents the highest level competition in China. I hope that the management organization can make a good rectification, and don't let the referee interfere in the game more, so that the game will be more ornamental and competitive.
