Perhaps you should try some spelling variations:
chieu bang » chieu sang, khien bang, chieu xanh
hanh tung » thanh tung, manh tung, hanh dung
cong cong » cong dong, trong cong, dung cong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
chu bang » thu bang, chuc nang, chu quang
anh tang » anh bang, anh dang, anh nang
toan ban » van 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 ((chieu bang) OR (chu bang)) - ((hanh tung) OR (anh tang)) cua cong cong manh toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu bang) or (chu bang)) - ((hanh tung) or (anh tang)) cua cong cong manh toan ban*.
