Perhaps you should try some spelling variations:
wang liang » wang yang
lang plan » lng plant, lang lang, plan plan
plan what » mean what
song ming » song bing, song min, gong min
can pain » hand pain, can aid, can pay
yang jie » yang jin, yang di, yang jui
yang yi » yang di, yang xi, yang jui

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: lang plan what can pain ((wang liang) OR (((yang yi) OR (yang jie)))) song ming ;~.
• Adding a wildcard symbol may retrieve word variants: lang plan what can pain ((wang liang) or (((yang yi) or (yang jie)))) song ming ;*.
