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

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: wang dan ((yang lu) OR (yang du)) ((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 ((yang lu) OR (yang du)) ((yi zhang) or (yi chang)) ming ((non ghi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan ((yang lu) OR (yang du)) ((yi zhang) or (yi chang)) ming ((non ghi) or (hong hai)) ;*.
