wang yang » wang yan, wang liang, wang yanling
zeng doug » zeng douglas
jeng dong » eng hong
li last » i last, als last, die last
a last » _ last, a las
thing » things, think, thin
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: wang wang yang ((li last) OR (a last)) thing ((zeng doug) OR (jeng dong)) sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yang ((li last) or (a last)) thing ((zeng doug) OR (jeng dong)) sin ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yang ((li last) or (a last)) thing ((zeng doug) OR (jeng dong)) sin ;*.
