Merge? Choe Hui-jeong

In the Chinese version of Shaolin and Taichi (http://hkmdb.com/db/movies/view.mhtml?id=11551), a mysterious "Tsui Ting" (??) with no other roles is fourth-billed, while the Korean actress with the same last name, Choe Hui-jeong, is uncredited. In the Korean advertising materials for this movie, Choe Hui-jeong is similarly billed (below Han Ying), so it seems to me like this is an alias for her. I haven't seen the movie, so if someone who has could confirm she has a prominent enough role to be fourth-billed, that would be useful.
