Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhieu tang » chieu sang, hieu lang, nhiet nang
hanh manh » hanh mang, lanh manh, hoang manh
dung cong » dung trong
manh cua » doanh cua, ban cua
cua dung » cua dang, cua dong, qua dung
van toan » van tuan, van tan, van thanh
dan than » dan chan, ban than, van than

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 xanh) OR (nhieu tang)) - hanh manh cua dung cong ((van toan) OR (dan than)) ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (nhieu tang)) - hanh manh cua dung cong ((van toan) or (dan than)) ban*.
