chang hsun » chang ch'un, chung hsuan, chang su
lang yuan » fang yuan, wang yuhan, meng yuan
hsun gain » run gain
yang yang » wang yang, wang yan
yang jin » yang jie, yang jun, ying jin
long han » long chain, long thanh, long haul
yang xi » yang di, yang yi, yang jui

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: lang yuan chang hsun gain ((((yang yang) OR (yang xi))) OR (yang jin)) long han ;~.
• Adding a wildcard symbol may retrieve word variants: lang yuan chang hsun gain ((((yang yang) or (yang xi))) or (yang jin)) long han ;*.
