Perhaps you should try some spelling variations:
wang liang » wang yang
liang yan » liang dan, liang tan, liang ying
khan sher » han shen, khan syed, than she
chang min » zhang ming, chang mae, chang won
chang ann » chang won, chang yun, change annex
chan ming » kian ming, chan eng, chan fong
zhong zhi » zhang zhi, hong ghi, zhong tai
yan khan » yar khan, yan zhang, zayn khan

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 liang yan khan sher ((((chang min) OR (chang ann))) OR (chan ming)) zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang yan khan sher ((((chang min) or (chang ann))) or (chan ming)) zhong zhi ;*.
