Perhaps you should try some spelling variations:
dong sign » dong sin, among sign, dong bin
hua last » a last
his last » als last, his host, his land
rong hai » hong hai, dang hai, long han
wan yan » wang yan, nan yan, wai yan
five hi » five high
hi rong » shi rong, yi rong, li rong

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 sign)) ya ((hua last) OR (his last)) five hi rong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (dong sign)) ya ((hua last) OR (his last)) five hi rong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong sign)) ya ((hua last) OR (his last)) five hi rong hai ;*.
