Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
dong sign » dong sin, among sign
dong bin » dong sin, dong di, dann bin
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
hua ren » hua chen
yan thi » yan zhi, tran thi, dang thi

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yong) or (((dong sign) or (dong bin)))) ya hua ren yan thi ((hong ghi) OR (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (((dong sign) OR (dong bin)))) ya hua ren yan thi ((hong ghi) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (((dong sign) or (dong bin)))) ya hua ren yan thi ((hong ghi) OR (hong hai)) ;*".
