Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung cua » truong cua, trung tuan, trung cap
hang cong » dang cong, hang nong, thanh cong
bang cong » dang cong, bang song, dung cong
ho trieu » mot trieu, 25 trieu, 30 trieu
toan cau » toan ban, toan tap, toan tai
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 trung cua ((hang cong) OR (bang cong)) dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - thanh trung cua ((hang cong) or (bang cong)) dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh trung cua ((hang cong) or (bang cong)) dan ((toan cau) OR (toan cao))*.
