Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
hongli hai » hong hai
yan liang » wang liang, you liang, yan wang
phong sau » wong sau
dan yang » daun yang, tan yang, wang yang
wong sam » wong sau, wong lai, kong sar
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan liang) OR (yang liang)) dan yang hongli hai ((phong sau) or (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan liang) OR (yang liang)) dan yang hongli hai ((phong sau) OR (wong sam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan liang) OR (yang liang)) dan yang hongli hai ((phong sau) or (wong sam)) ;*".
