Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yang liang » wang liang, yan liang, yang yang
hong tran » hong tan, tung tran
tran than » tran thanh, tran trang, tran thien
yang jie » yang jin, yang di, yang jui
hong yu » wong yue
test » 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 tran than china (rest OR (test OR text)) ((yang jie) OR (yang liang)) hong yu ;~.
• Adding a wildcard symbol may retrieve word variants: hong tran than china (rest or (test or text)) ((yang jie) or (yang liang)) hong yu ;*.
