yan guan » gan guan, yan yuan, yang guang
gui guan » gan guan, gui hua, tuo guan
wai yan » wang yan, wei yang
dong di » dong sin
ming li » ling li, ming lu, ming yi

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wai yan) OR (dong di)) ((yan guan) OR (gui guan)) ming li ((gang dong) OR (gang gong)) sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (dong di)) ((yan guan) or (gui guan)) ming li ((gang dong) OR (gang gong)) sin ;*".
