Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
shang hai » shang kai, dang hai, chang ha
yang yan » yang yang, wang yan, yang fan
yan chia » tan chia, can china, dan china
dan yang » daun yang, tan yang, yang yang
tan yong » tan hong, tan kong, tan yang
zong hai » hong hai, dang hai, long 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 yang yan chia ((dan yang) OR (tan yong)) lin ((zong hai) OR (shang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang yan chia ((dan yang) or (tan yong)) lin ((zong hai) or (shang hai)) ;*.
