There is a mainland MMA fighter ???, he definitely was in The King of Streets (2012) http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng and Undercover Duet (2015) - http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

But in the database one movie stars http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng and second stars http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng
I guess that he stars in Imprisoned (2015) too (cause its made by same people who made Undercover Duet) but I doubt he was in Full Throttle (he was 6 at the time) and taiwanese My Wishes (he was 10). Although I don't know if he was in Almost Perfect (2008) http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

If nobody stops me in 15 days I will split them.
