Perhaps you should try some spelling variations:
wang liang » wang yang
wang ying » wang yang, wang yong, wang jing
wang ning » wang jing, wang yang, wang yong
phan ying » zhang ying, fan ying, ran ying
ying zeng » yin peng, ying yang
zeng doug » jeng dong, zeng douglas
wang van » wang yan, wang ban, wang dan
van phan » dan phan, van thanh, van ham
doug hai » dang hai, hong hai

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 ying) OR (wang ning))) OR (wang liang)) wang van phan ying zeng doug hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang ying) or (wang ning))) or (wang liang)) wang van phan ying zeng doug hai ;*.
