Perhaps you should try some spelling variations:
yuan kang » yuan chang, chan kang, yuan kai
yuan wang » yan wang, yuan chang, qian wang
dong bin » dong di, dann bin
hong hai » shang hai, zhong tai, dang hai
hong ghi » zhong zhi, hong g
han min » han men, kan min, chan ming
sin » sign, sind, skin

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

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