Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, mot chieu
tac thanh » bac thanh, cac thanh, tcc thanh
thanh cac » hanh cac, thanh bac, thanh ca
ho chieu » theo chieu, hoc thieu, mot chieu
cong tac » cong ty
mang va » mang vua, hang va, dang va
bang va » hang va, ban va, trang va

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 chieu) OR (doi chieu)) sang - nhanh ((mang va) OR (bang va)) nhung cong tac thanh cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) sang - nhanh ((mang va) or (bang va)) nhung cong tac thanh cac~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) sang - nhanh ((mang va) or (bang va)) nhung cong tac thanh cac*.
