Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
lang yan » wang yan, wang yang, zhang yan
yan ying » fan ying, ran ying, tan ying
ying hua » ming hua, wang hua, ying zhu
tan yang » dan yang, tan ying, tan yong
hua tan » hua ban, huan t'an
hong a » hong ma, hong w, kong 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: lang yan ying hua tan yang di ((shang hai) OR (hong a)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ying hua tan yang di ((shang hai) or (hong a)) ;*.
