Perhaps you should try some spelling variations:
thanh tang » thanh thang, thanh trang, thanh tung
thi thong » thi thuong, thi hong, thi khong
ho trieu » mot trieu, 25 trieu, 30 trieu
tang thi » dang thi, tang tai, hoang thi
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
toan cau » toan cao, toan ban, toan tap

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 tinh - thanh tang thi thong ((cong tan) OR (cong san)) ((phan tu) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - thanh tang thi thong ((cong tan) OR (cong san)) ((phan tu) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh tang thi thong ((cong tan) OR (cong san)) ((phan tu) or (toan cau))*.
