Perhaps you should try some spelling variations:
gang dong » gang gong, gang sung, jeng dong
yan guan » yan yuan, yang guang, yihan guan
gan guan » quan guan, fan guon, gui guan
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, qian yan
lu gang » liu gang, li gang, xu gang
sin » sign, sind, skin

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: ((wan yan) OR (dong di)) ((((yan guan) OR (nan yan))) OR (gan guan)) ming lu gang dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong di)) ((((yan guan) or (nan yan))) or (gan guan)) ming lu gang dong sin ;*.
