Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, truong thanh
tran tuan » tran xuan, tran quang, tran thanh
dung cong » dung trong
ho trieu » mot trieu, 25 trieu, 30 trieu
cong san » cong tac
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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 ((trung tuan) OR (tran tuan)) dung cong san ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - thanh ((trung tuan) or (tran tuan)) dung cong san ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh ((trung tuan) or (tran tuan)) dung cong san ((than cau) OR (than cap))*.
