Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » truong cua, trung tuan, trung cap
tung cua » tuong cua, dung cua, tang cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan 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: ho ((hieu manh) OR (trieu tinh)) - thanh ((tung cua) OR (trung cua)) nhung cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (trieu tinh)) - thanh ((tung cua) OR (trung cua)) nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (trieu tinh)) - thanh ((tung cua) OR (trung cua)) nhung cong tan toan tap*.
