Perhaps you should try some spelling variations:
wang yidan » wang yan
wang yang » wang yan, wang liang, wang yanling
xiao yang » xiao zhang, xia fang, xiao yuan
tan chia » tuan china, than china, can china
tan puay » tan hua
dan yang » daun yang, tan yang, yang yang
le dang » le sang, le duong
hai » hadi, haji, hari

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 yidan ((tan chia) OR (tan puay)) ((((dan yang) OR (wang yang))) OR (xiao yang)) le dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan ((tan chia) or (tan puay)) ((((dan yang) or (wang yang))) or (xiao yang)) le dang hai ;*.
