Perhaps you should try some spelling variations:
chan ming » kian ming, chan eng, chan fong
yang yang » wang yang, wang yan
jeong hai » jeong han, jeong mi, jeong nam
hong hai » shang hai, zhong tai, dang hai
dong di » dong sin
han min » han men, kan min, chang min
a main » 1 main, 2 main
ya a » a a, y a, ye a

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (dong di)) ya a main ((han min) OR (chan ming)) ((jeong hai) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (dong di)) ya a main ((han min) OR (chan ming)) ((jeong hai) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (dong di)) ya a main ((han min) OR (chan ming)) ((jeong hai) or (hong hai)) ;*".
