Perhaps you should try some spelling variations:
lang plan » lng plant, lang lang, plan plan
plan what » mean what
yang yang » wang yang, wang yan
song ming » song bing, song min, gong min
what run » what can
run gain » run pain
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 run gain ((yang yang) OR (((yang yi) OR (yang jie)))) song ming ;~.
• Adding a wildcard symbol may retrieve word variants: lang plan what run gain ((yang yang) or (((yang yi) or (yang jie)))) song ming ;*.
