Perhaps you should try some spelling variations:
wang liang » wang yang
liang rong » qian rong, liang ying, zhang rong
khan sher » han shen, than she
khan syed » ahsan syed, shah syed
chang min » zhang ming, chang mae, chan ming
hong ng » hong jong, hong hong
kong » long, pong, ong

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 rong ((khan sher) OR (khan syed)) chang min ((hong ng) OR (hong kong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang rong ((khan sher) OR (khan syed)) chang min ((hong ng) or (hong kong)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang rong ((khan sher) OR (khan syed)) chang min ((hong ng) or (hong kong)) ;*.
