Perhaps you should try some spelling variations:
zhang ming » zhang xin
tong shui » tong hui, cong shu, gong hui
kong shu » cong shu, kong sar, kong eiu
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, nan yan, wai yan
yang yi » yang di, yang xi, yang jui
yan zi » yan zhi, yuan zi, ban zi
zhen » zheng, when, chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan ((yang yi) or (yan zi)) zhen zhang ming ((((kong shu) OR (kong siu))) or (tong shui)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((yang yi) OR (yan zi)) zhen zhang ming ((((kong shu) OR (kong siu))) OR (tong shui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang yi) or (yan zi)) zhen zhang ming ((((kong shu) OR (kong siu))) or (tong shui)) ;*".
