Perhaps you should try some spelling variations:
thanh trung » thanh tung
tien thanh » tien thinh, tran thanh, den thanh
trung tuan » trung thanh, trung tam, tran tuan
tuan trong » thuan trong, quan trong, tran trong
hien xanh » hien hanh, hien nhanh, chieu xanh
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: hoc ((hien xanh) OR (tien thanh)) - thanh trung tuan trong cong tan toan tap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (tien thanh)) - thanh trung tuan trong cong tan toan tap*.
