yang jin » yang jun, ying jin, shang jin
yang xi » yang di, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan joon chang you chen ((((yang jie) or (yang jin))) or (((yang xi) OR (yang yi)))) dang hadi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan joon chang you chen ((((yang jie) OR (yang jin))) OR (((yang xi) OR (yang yi)))) dang hadi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan joon chang you chen ((((yang jie) or (yang jin))) or (((yang xi) OR (yang yi)))) dang hadi ;*".
