Perhaps you should try some spelling variations:
wang liang » wang yang
san using » plan using, mean using, win using
wang san » wang yan, wang ban, wang dan
using ai » using a, using big, using _
tan yang » dan yang, tan ying, tan yong
gang hai » dang hai, shang hai, gang hu
eang hay » dang hai, kang han

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 san using ai ((wang liang) OR (tan yang)) yi ((gang hai) OR (eang hay)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang san using ai ((wang liang) or (tan yang)) yi ((gang hai) OR (eang hay)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang san using ai ((wang liang) or (tan yang)) yi ((gang hai) OR (eang hay)) ;*.
