Perhaps you should try some spelling variations:
shang kai » shang hai
long tan » hong tan, long han, long thanh
tan kong » tan hong
kong yue » wong yue, kong your, kong yam
yue chen » yu chen, yun chen, yulu chen
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang xi
yang yi » yang xi

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: long tan kong yue chen ((((yang jun) OR (yang jui))) OR (((yang yi) OR (yang di)))) shang kai ;~.
• Adding a wildcard symbol may retrieve word variants: long tan kong yue chen ((((yang jun) or (yang jui))) or (((yang yi) or (yang di)))) shang kai ;*.
