Perhaps you should try some spelling variations:
yang liang » yan liang, yang yang, peng liang
wang liang » wang yang
tan chia » tuan china, than china, can china
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
tan tan » tas tan, tin tan, tang tang
hong » long
test » text, west, best

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: hong tan tan chia (rest OR test) ((yang jin) OR (((yang liang) OR (wang liang)))) wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hong tan tan chia (rest or test) ((yang jin) or (((yang liang) OR (wang liang)))) wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: hong tan tan chia (rest or test) ((yang jin) or (((yang liang) OR (wang liang)))) wong yue ;*.
