Perhaps you should try some spelling variations:
yang yao » yang yang, wang yan, yang yi
den gang » deng gang, der gang, den umgang
song ghi » hong ghi, song shin, song li
yang ka » yang fan
hua den » hua ren, hua chen
gang li » gan li, tang li, wang li
li song » li cong, li rong, kim song

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 ((yang di) OR (((((yang ka) OR (yang yao))) OR (yang dean)))) hua den gang li song ghi ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang di) or (((((yang ka) or (yang yao))) or (yang dean)))) hua den gang li song ghi ;*.
