Perhaps you should try some spelling variations:
yang liang » yan liang, yang yang, peng liang
wang yang » wang yan, wang yanling
gang tin » lang tim
tin hong » tan hong, kia hong, thi hong
yang li » yang lin, yang di, yang xi
li gang » liu gang, ii gang, i gang
hong du » hong yu, long du, hong tou

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