Who is Li Na's tennis coach?

Li Na and Zheng Jie have both launched national teams! Li na was an old man when she was in the national team ~ her husband was in charge of physical training! Now her husband is an assistant coach, and the real coach is himself. Just like Federer! All coaches are auxiliary. It is important to give some advice when necessary. However, at present, coaches are not allowed to conduct on-site command, only to see the lack of comments on the performance of manufacturers. It may be that there are not so many restrictions on quitting the national team, so you can play more strategies. There is no need to respect the hard indicators of the country, and Jinhua Gate can get better and better. Of course, the state's support for them must be respected, otherwise they would not be today. You know, a year's travel accommodation costs 60WRMB, and few people have that much money to maintain it.
