Perhaps you should try some spelling variations:
shang kai » shang hai
tan chia » tuan china, than china, can china
chia tan » chia lan, chen tan, chia wen
yang jun » yang jui, yang jin, yang judy
pang jun » yang jui
wan yan » wang yan, nan yan, wai yan
yan tan » tan tan, yan clan, yan guan
hong g » hong ng, hong w, hong 7

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: wan yan tan chia tan ((yang jun) OR (pang jun)) ((shang kai) OR (hong g)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan tan chia tan ((yang jun) or (pang jun)) ((shang kai) or (hong g)) ;*.
