Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
dong sign » dong sin, among sign, dong bin
yuan ting » yuan ming, huang ting, yuan kang
yang lin » yang jin, yang li, yang liang
wang lin » wang li, wang qin, wang limin
gong hui » tong hui, tong shui, wang hui
ye a » yet a, e a, me a

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: ((zhang yan) OR (dong sign)) ye a west ((((yang lin) OR (wang lin))) OR (yuan ting)) gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) or (dong sign)) ye a west ((((yang lin) OR (wang lin))) or (yuan ting)) gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yan) or (dong sign)) ye a west ((((yang lin) OR (wang lin))) or (yuan ting)) gong hui ;*.
