Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong chan » fong chan, jong chan, long chain
hei shang » wei shang, hei sing, lei sheng
yang july » yang judy, yang jun
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang yi
yang xi » yang yi

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 yong chan hei shang ((((((yang di) OR (yang xi))) OR (yang jui))) OR (yang july)) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong chan hei shang ((((((yang di) or (yang xi))) or (yang jui))) or (yang july)) shang hai ;*.
