Perhaps you should try some spelling variations:
wang shiyong » wang hyoung
gain yang » dan yang, daun yang, tan yang
yun gain » run gain, you gain, n gain
eang hay » dang hai, kang han
yan yun » yan yuan, yang yun, yan kun
yang xi » yang di, yang yi, yang jui
xi eang » xi kang, xi zhang

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 shiyong) OR (wang yan)) yan yun gain yang xi eang hay ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang shiyong) or (wang yan)) yan yun gain yang xi eang hay ;*.
