Perhaps you should try some spelling variations:
gang dong » gang gong, gang sung, jeng dong
yan guan » yan yuan, yang guang, quan guan
gan guan » quan guan, fan guon, gui guan
wai yan » wang yan, wei yang
ming li » ling li, ming lu, ming yi
li gang » liu gang, ii gang, i gang
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wai yan) or (dong di)) ((((yihan guan) OR (yan guan))) or (gan guan)) ming li gang dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wai yan) OR (dong di)) ((((yihan guan) OR (yan guan))) OR (gan guan)) ming li gang dong sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (dong di)) ((((yihan guan) OR (yan guan))) or (gan guan)) ming li gang dong sin ;*".
