Perhaps you should try some spelling variations:
china zhang » china chang, cheng zhang, chin chang
zhang wei » zhen wei
wei liang » wei qiang, wee liang, wei shang
liang sun » liang dan, liang tan, wing sun
lang a » lang _, erlang a
lang 3 » klang 3, gang 3, lang _
wang » wing, wan

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((lang a) OR (lang 3)) china zhang wei liang sun ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((lang a) OR (lang 3)) china zhang wei liang sun ;*.
