The new Japanese table tennis star Ai Fukuhara, as early as last year when she participated in a table tennis match held in Xinjiang, bought a jade fly. This time she came to Doha, and specially asked a friend to bring a jadeite horse from Xinjiang. Before participating in the quarter-final, she put the fly on the horse's back, hoping to "win immediately", but as a result, she was defeated by Guo Yue, the new leading female table tennis player in China, after winning the first two games.
When she returned to the dormitory, she found that her original jadeite horse had broken a "leg", so she found the reason for the failure. The next day, when chatting about this matter, Chinese table tennis head coach Liu Guoliang teased Ai Fukuhara and said: "Do you know why you lost? It's not because your horse broke its leg, but because when you were in the match, I sent someone to your dormitory, took the fly off your jadeite horse, and put a book in its place, so you lost immediately." After hearing this, the 16-year-old Ai Fukuhara, whose face was melancholy, finally showed a happy smile.
