Perhaps you should try some spelling variations:
wang yuhan » wang luhang, wang yan, wang yidan
yuhan kai » yuan kai
yang mind » yang cindy, yang jin, sang minh
kai chai » ka chai, goi chai, kim chai
chai dan » chai onn, chai tam, shi dan
dan yang » daun yang, tan yang, wang yang
hong hai » shang hai, zhong tai, hong tan
chang ha » chang mae

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