Perhaps you should try some spelling variations:
shang kai » shang hai
yan yuan » yan guan, fang yuan, nan yan
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
yan yan » nan yan, yang yang, wang yan
hua tan » hua ban, huan t'an
hong g » hong ng, hong w, hong a
hong 7 » hong w, hong a
wang » wing, 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 ((yan yan) OR (yan yuan)) hua tan yang jin ((shang kai) OR (((hong g) OR (hong 7)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) or (yan yuan)) hua tan yang jin ((shang kai) or (((hong g) OR (hong 7)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yan) or (yan yuan)) hua tan yang jin ((shang kai) or (((hong g) OR (hong 7)))) ;*.
