Perhaps you should try some spelling variations:
last thin » last thing, last things
zeng doug » zeng douglas
jeng dong » eng hong
yan jin » yang jin, yang jing, yang jie
yan jiu » yang jie, yang jin, pang jiu
li last » i last, als last, die last
wang » wing, wan, lang
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 ((yan jin) OR (yan jiu)) li last thin ((zeng doug) OR (jeng dong)) sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan jin) OR (yan jiu)) li last thin ((zeng doug) or (jeng dong)) sin ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan jin) OR (yan jiu)) li last thin ((zeng doug) or (jeng dong)) sin ;*.
