Perhaps you should try some spelling variations:
thanh trung » thanh tung
hien nhanh » thien thanh, tien thanh, dien thanh
trung tuan » trung thanh, trung tam, tran tuan
tuan nhung » quan nhung, tuan hung, thuat nhung
nhung cong » dung cong, thong cong, hang cong
hien hanh » dieu hanh
cong tan » cong tac, cong san, cong thanh
hang vau » hang dau, hang cau, hang vat

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: hoc ((hien nhanh) OR (hien hanh)) - thanh trung tuan nhung cong tan ((hang vau) OR (hang va))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) OR (hien hanh)) - thanh trung tuan nhung cong tan ((hang vau) or (hang va))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) OR (hien hanh)) - thanh trung tuan nhung cong tan ((hang vau) or (hang va))*.
