He linked the match to his life, and said he did not want to burden himself. The Chinese team will lose a game this time, but no one will win the rule 3-0, so there is no need to give it to oneself. Liu Guoliang said, in fact, not only is the competition, but each of us should face the difficulties in life in this way. Later, Liu Guoliang continued to add: there are problems that need to be carried and carried. Such a team is strong. It can be seen that Liu Guoliang can understand the connotations of the game both technically and psychologically. A long-term competitive sports career can really set up a positive and optimistic attitude towards life for a person. Liu Guoliang said frankly, at the first time, he wrote a letter to Ding Ning for losing the ball, told her to learn to forget and play the final match well.
