I have no idea about the list. But the Asian champions allows 10 athletes per gender so it’s still not easy to say who will grab the Olympic quota. I am pretty sure only Asian champion will get the quota still it’s not a guarantee. Based on my searching, all 2019 WCH champions are preparing for it.
Edit: I found a list of 11 athletes per gender attended a NT internal competition for the preparation of Asian CH on March.
Women: Hou Zhihui, Jiang Huihua, Liao Qiuyun, Li Yajun, Luo Xiaomin, Deng Wei, Huang Ting, Zhang Wangli, Wang Zhouyu, Kang Yue, Li Wenwen
Men: Li Fabin, Chen Lijun, Huang Minhao, Feng Lyudong, Shi Zhiyong, Yuan Chengfei, Lyu Xiaojun, Li Dayin, Tian Tao, Tian Fuxuan, Yang Zhe
