ting you » thing you, bring you, ting kok
you gain » you can
yang jin » yang jie, yang jun, ying jin

long han » long chain, long thanh, long haul

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 zhang ting you gain ((((yang jin) OR (yang jui))) OR (yang di)) long han ;~.
• Adding a wildcard symbol may retrieve word variants: wang zhang ting you gain ((((yang jin) or (yang jui))) or (yang di)) long han ;*.
