jeng dong » eng hong, zeng doug
dong sign » dong sin, among sign, dong bin
wing yan » wang yan, wing ian, wing tan
als last » als gast, a last, its last
his last » his host, his land, its last
thing » things

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: wing yan zwang ((als last) OR (his last)) ((thing OR think) OR thin) jeng dong sign ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan zwang ((als last) OR (his last)) ((thing or think) or thin) jeng dong sign ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan zwang ((als last) OR (his last)) ((thing or think) or thin) jeng dong sign ;*.
