sin long » since long, using long, pain long
yang xi » yang di, yang yi, yang jui
li dong » li cong, li rong, kim dong

long do » long d, long du, longer do

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 wang) OR (wang yang)) yang xi ((li dong) OR (li song)) sin long do ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) yang xi ((li dong) or (li song)) sin long do ;*.
