hyoung tuan » hyoung gun
tuan hua » tan hua, tuan vu, yuan hui
hua rein » hua ren, hua wei, a rein
pang jiu » pang jun, yang jie, pan ji
yang jin » yang jie, yang jun, ying jin

• Adding a wildcard symbol may retrieve word variants: wing hyoung tuan hua rein ((((yan jiu) or (pang jiu))) or (yang jin)) long run ;*.
