Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
theo bien » thieu bien, che bien, pho bien
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
toan cao » toan ban
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: ((theo bien) OR (theo tieu)) tinh - thanh trung cua nhung cong dan ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo bien) OR (theo tieu)) tinh - thanh trung cua nhung cong dan ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((theo bien) OR (theo tieu)) tinh - thanh trung cua nhung cong dan ((toan cao) or (toan tap))*.
