Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
thi nhung » thi nang, thi hong, thi huong
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
cong van » cong vang, cong san, song van
van phan » van phong, van thanh, luan phan
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: ((ho trieu) OR (30 trieu)) tinh - ((thanh trung) OR (thanh tung)) thi nhung cong van phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - ((thanh trung) or (thanh tung)) thi nhung cong van phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - ((thanh trung) or (thanh tung)) thi nhung cong van phan cau*.
