chih sing » chih p'ing, chih hang, chih yung
dong sind » dong sin, dong bin
dong ping » dong sin, dong bin, dong jung
yan guan » gan guan, yan yuan, yang guang
nan yan » nan ya, wang yan, qian yan
yi chen » jui chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang ((((nan yan) or (yang yang))) or (yan guan)) yi chen chih sing ((dong sind) OR (dong ping)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((((nan yan) OR (yang yang))) OR (yan guan)) yi chen chih sing ((dong sind) OR (dong ping)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((nan yan) or (yang yang))) or (yan guan)) yi chen chih sing ((dong sind) OR (dong ping)) ;*".
