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
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang yi
yang xi » yang yi

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "kang china hong yun gain ((((((yang 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 ((((((yang jin) OR (yang jui))) OR (yang xi))) OR (yang di)) long green ;*.
