yan guan » gan guan, yan yuan, yang guang
yang yun » yang jun, tang yun, yang yue
tan yang » dan yang, tan ying, tan yong
ii chang » yi chang, ii changes, iii change

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan hyoung ((((yan guan) or (yang yun))) or (nan ya)) tan yang ((ii chang) OR (vii chang)) chuan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung ((((yan guan) OR (yang yun))) OR (nan ya)) tan yang ((ii chang) OR (vii chang)) chuan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung ((((yan guan) or (yang yun))) or (nan ya)) tan yang ((ii chang) OR (vii chang)) chuan ;*".
