Thats the tournament where zhu ting almost fainted and i remember she was carried
That was different, that was the 全运会 (National Games of China) which occurs every post-olympic year (e.g. 2013, 2017, etc). It's a multidisciplinary event, not the National Championship which happens every year.
The National Games is more important in terms of players and coaches getting benefits after retirement, but for a player of Zhu Ting's caliber they're peanuts. Still, she chooses to represent her home province Henan.
