Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, hong hai
lang yan » wang yan, wang yang, zhang yan
than tan » tan tan, othman tan, than rain
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
chang ha » chang mae
yan ka » yang ka, yuan kai

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 ka than tan yang jin ((shang hai) OR (chang ha)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ka than tan yang jin ((shang hai) or (chang ha)) ;*.
