Perhaps you should try some spelling variations:
shang kai » shang hai
chai tan » chai tam, chai onn
tan yong » tan hong, tan kong, tan yang
yong jin » yang jin, ying jin, song jin
hong hai » shang hai, zhong tai, dang hai
yan kim » tan kim, yap kim, hwan kim
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 kim) OR (yong kim)) chai tan yong jin ((hong hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan kim) OR (yong kim)) chai tan yong jin ((hong hai) or (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan kim) OR (yong kim)) chai tan yong jin ((hong hai) or (shang kai)) ;*.
