Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, chau tinh, kieu tinh
lieu tinh » trieu tinh, diep tinh, bien tinh
canh manh » lanh manh, canh tranh, cach mang
chua bang » chu bang, chua nang, chua xang
cua dang » cua cong, cua ban
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cao » toan cao, thai cao, than cap

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 (lieu tinh)) - canh manh ((chua bang) OR (cua dang)) cong tan than cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) or (lieu tinh)) - canh manh ((chua bang) or (cua dang)) cong tan than cao*.
