Perhaps you should try some spelling variations:
wang yidan » wang yan
wang dan » wang yan, wang ban, wang yang
yi zhang » li zhang, xi zhang, bin zhang
yi chang » ii chang, ying chang, jin chang
hong hai » shang hai, zhong tai, dang hai
non ghi » hong ghi
yang d » yang di, yang du, yang _

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dan) OR (wang yidan)) yang d ((yi zhang) or (yi chang)) ming ((non ghi) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) yang d ((yi zhang) OR (yi chang)) ming ((non ghi) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) yang d ((yi zhang) or (yi chang)) ming ((non ghi) or (hong hai)) ;*".
