yang yang » wang yang, wang yan
tang min » chang min, sang minh, yang mind
hong ghi » zhong zhi, hong g, hong hai
yan yan » yan yuan, nan yan, wang yan
li tang » li gang, li tana, li wang
zhi li » zhi ji

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((yan yan) OR (yang yang)) zhi li tang min ((hong ghi) OR (zhang zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((yan yan) or (yang yang)) zhi li tang min ((hong ghi) or (zhang zhi)) ;*.
