Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
tung tuan » trung tuan, quang tuan, trang tuan
hung tuan » hung tran, quang tuan, trung tuan
ho trieu » mot trieu, 25 trieu, 30 trieu
ban cong » bang cong, van cong, phan cong
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 ((tung tuan) OR (hung tuan)) ban cong thanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh ((tung tuan) OR (hung tuan)) ban cong thanh toan ban*.
