yan long » yan cong, van long, pain long
long can » long han, long chain, long call
can risk » chain risk
tan long » tan hong, van long, pain long
tan yong » tan hong, tan yang, tan ying
tan kong » tan hong

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: wing yan long can risk sharing ((tan long) OR (((tan yong) OR (tan kong)))) arm ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan long can risk sharing ((tan long) or (((tan yong) OR (tan kong)))) arm ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan long can risk sharing ((tan long) or (((tan yong) OR (tan kong)))) arm ;*.
