Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhieu tang » chieu sang, hieu lang, nhiet nang
hanh dung » thanh dung, anh dung, hanh dong
dang cong » dung cong
dung cua » dung luan, dung cho
cua dang » cua cong, cua ban
tan toan » tap toan, van toan, dan toan

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: theo ((chieu tinh) OR (nhieu tang)) - hanh dung cua dang cong ((tan toan) OR (tan tran)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (nhieu tang)) - hanh dung cua dang cong ((tan toan) or (tan tran)) cau*.
