taizong tang » tang tang
tang huan » wang hua, tan hua, tang chun
t'an yang » tan yang, dan yang, tao yang
yi kang » yi yang, jin kang, yi chang
xi kang » jin kang, xi zhang
yi gang » ii gang, i gang, li gang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang taizong tang huan t'an yang ((((yi kang) OR (xi kang))) or (yi gang)) han ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang taizong tang huan t'an yang ((((yi kang) OR (xi kang))) OR (yi gang)) han ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang taizong tang huan t'an yang ((((yi kang) OR (xi kang))) or (yi gang)) han ;*".
