Perhaps you should try some spelling variations:
zhang ming » zhang xin
tong shui » tong hui, cong shu, gong hui
yan clan » das clan, yan guan, yan yuan
kong shu » cong shu, kong siu, kong sar
yan gan » yan guan, yan wang, yan yuan
li zhen » li chen, li zhenan, li zhang
wang » wan, lang

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 OR wing) ((yan gan) OR (yan clan)) li zhen zhang ming ((kong shu) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan gan) or (yan clan)) li zhen zhang ming ((kong shu) OR (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan gan) or (yan clan)) li zhen zhang ming ((kong shu) OR (tong shui)) ;*.
