Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
chau tinh » ha tinh, cua tinh, cac tinh
cua khong » hua khong, cua phuong, cua thuong
anh tang » anh bang, anh dang, anh sang
anh nang » ganh nang, anh bang, anh dang
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » toan cao, toan ban, toan tap

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 ((chau tinh) OR (cuu tinh)) - ((anh tang) OR (anh nang)) cua khong cong tac toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chau tinh) or (cuu tinh)) - ((anh tang) or (anh nang)) cua khong cong tac toan cau*.
