Perhaps you should try some spelling variations:
shang kai » shang hai
wang yang » wang yan, wang liang, wang yanling
yang yan » yang yang, wang yan, yang fan
tan yong » tan hong, tan kong, tan yang
yong jun » yang jun, dong jung, yang jui
yan hua » tan hua, ya hua, wang hua
hua tan » hua ban, huan t'an
hong 7 » hong w, hong a, hong g

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 yang yan hua tan yong jun ((shang kai) OR (hong 7)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang yan hua tan yong jun ((shang kai) or (hong 7)) ;*.
