Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tang » hanh trang, anh tang, hanh mang
dang cong » dung cong
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chu manh, chua xang, chuc danh
van toan » van tuan, van tan, van thanh
tang va » trang va, tang van, thang va
va dang » van dang, va nang, va lang

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 va dang cong ((manh toan) OR (van toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chieu xanh)) - hanh tang va dang cong ((manh toan) or (van toan)) cau*.
