chou chih » chen chih
chih sing » chih p'ing, chih hang, chih yung
sing dong » sing kong, jeng dong, shin dong
yan yuan » fang yuan, nan yan, yan kun
yan clan » das clan
yan guan » gan guan, yihan guan, quan guan
dong bin » dong sin, dong di, dann bin

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

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