Perhaps you should try some spelling variations:
chuan when » can when
when gong » when songs, when good, when goal
hong shui » tong shui, cong shu, gong hui
yang yao » yang yang, wang yan, yang yi
gong min » jong min, song min, gong meng
tong hui » wang hui
yang ka » yang fan

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: yang ((yang ka) OR (yang yao)) chuan when gong min ((hong shui) OR (tong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yang ka) or (yang yao)) chuan when gong min ((hong shui) OR (tong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((yang ka) or (yang yao)) chuan when gong min ((hong shui) OR (tong hui)) ;*.
