Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
mot trieu » mot chieu, mot tri, mon triet
trung cua » truong cua, trung tuan, trung cap
tang cua » mang cua, hang cua, tang luan
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
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: mot trieu tinh - hanh ((tang cua) OR (trung cua)) nhung cong tac toan cao~.
• Adding a wildcard symbol may retrieve word variants: mot trieu tinh - hanh ((tang cua) or (trung cua)) nhung cong tac toan cao*.
