Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, hong hai
yang mind » yang cindy, yang jin, sang minh
yuan kai » yuan kang, yuan fei, tan kai
chai tan » chai tam, chai onn
tan yang » dan yang, tan ying, tan yong
chang ha » chang mae
yan ka » yang ka
wang » wing, wan, lang

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 ((yan ka) OR (yuan kai)) chai tan yang mind ((shang hai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan ka) OR (yuan kai)) chai tan yang mind ((shang hai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan ka) OR (yuan kai)) chai tan yang mind ((shang hai) or (chang ha)) ;*.
