Perhaps you should try some spelling variations:
kang china » kong china, hang china, ming china
long green » going green, long grain
hong yun » chong yun, hong yu, song yun
yun gain » run gain, you gain, n gain
ying jin » yang jin, jing ji, yang jie
yang jui » yang judy, yang yi
yang xi » yang yi

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: kang china hong yun gain ((((((ying jin) OR (yang jui))) OR (yang xi))) OR (yang di)) long green ;~.
• Adding a wildcard symbol may retrieve word variants: kang china hong yun gain ((((((ying jin) or (yang jui))) or (yang xi))) or (yang di)) long green ;*.
