Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung tuan » trung thanh, trung tam, tran tuan
ho trieu » mot trieu, 25 trieu, 30 trieu
tuan ban » tuan bang, luan ban, quang ban
ban cong » bang cong, van cong, phan cong
toan cao » toan tap
toan ban » van ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - thanh trung tuan ban cong trinh ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh trung tuan ban cong trinh ((toan cao) OR (toan ban))*.
