Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yang liang » yan liang, yang yang, peng liang
wang liang » wang yang
tan than » tan tan, tran thanh, tan shawn
yang jin » yang jie, yang jun, ying jin
hong yu » wong yue
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 than china (rest OR test) ((yang jin) OR (((yang liang) OR (wang liang)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hong tan than china (rest or test) ((yang jin) or (((yang liang) OR (wang liang)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: hong tan than china (rest or test) ((yang jin) or (((yang liang) OR (wang liang)))) hong yu ;*.
