Perhaps you should try some spelling variations:
song qing » song bing, song ming, gong qiang
long hour » long hours, long haul
yan yang » yang yang, dan yang, tan yang
yao yang » yang yang
long dou » long du, long did, long d
lu song » li song, kyu song, yun song
long do » long d, long du, longer do
li lu » li ju, li l, li li
wang » wing, wan, lang

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 ((yan yang) OR (yao yang)) li lu song qing ((((long dou) OR (long hour))) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) or (yao yang)) li lu song qing ((((long dou) OR (long hour))) or (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) or (yao yang)) li lu song qing ((((long dou) OR (long hour))) or (long do)) ;*.
