Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
tuan trong » thuan trong, quan trong, tran trong
hoc thieu » toc thieu
tran tuan » tran xuan, tran quang, tran thanh
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
phan cau » phan dau, phan cac, phan tu

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 thieu) OR (hoc hien)) tinh - thanh tran tuan trong ((cong dan) OR (cong san)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) tinh - thanh tran tuan trong ((cong dan) OR (cong san)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) tinh - thanh tran tuan trong ((cong dan) OR (cong san)) phan cau*.
