Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
hang cong » dang cong, hang nong, bang cong
tong cong » trong cong, cong cong, dung cong
chu xanh » chu manh, chua xang, chuc danh
van tuan » van quan, van ban, anh tuan
tuan ban » tuan bang, toan ban, luan ban

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 ((chu xanh) OR (chieu xanh)) - hanh tang luan ((hang cong) OR (tong cong)) van tuan ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chieu xanh)) - hanh tang luan ((hang cong) or (tong cong)) van tuan ban*.
