ying yang » yang yang, yin yang, ying chang
yuan kai » yuan kang, yuan fei, yuan hui
yang jin » yang jie, yang jun, ying jin
jin dang » jin kang, jin chang, jing fang
tan kai » tan kah
hai » hadi, haji, hari

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 ying yang ((yuan kai) OR (tan kai)) yang jin dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang ying yang ((yuan kai) or (tan kai)) yang jin dang hai ;*.
