Perhaps you should try some spelling variations:
gang tan » liang tan, tang tang, hong tan
yuan li » yuan lin, guan li, yuan zi
yang li » yang lin, yang xi, yang yi
li gang » liu gang, ii gang, i gang
hong du » hong yu, long du, hong tou
yan li » gan li, tan li, yan zi
wang » wing, wan, lang

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 ((((yan li) OR (yuan li))) OR (((yang li) OR (yang di)))) li gang tan hong du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yan li) or (yuan li))) or (((yang li) OR (yang di)))) li gang tan hong du ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yan li) or (yuan li))) or (((yang li) OR (yang di)))) li gang tan hong du ;*.
