yang yun » yang jun, tang yun, yang yue
yun gain » run gain, you gain, n gain
yang li » yang lin, yang yi, tang li
yang xi » yang yi, yang jui
yang » ryang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang kyoung) OR (wang yong)) yang yun gain ((((yang li) or (yang xi))) or (yang di)) wang yan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang kyoung) OR (wang yong)) yang yun gain ((((yang li) OR (yang xi))) OR (yang di)) wang yan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang kyoung) OR (wang yong)) yang yun gain ((((yang li) or (yang xi))) or (yang di)) wang yan ;*".
