Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thong cap » thong cac, trung cap, thong cua
cong vang » cong lang, cong quang, cong ngang
ho trieu » mot trieu, 25 trieu, 30 trieu
tung cap » trung cap, cung cap, trong cap
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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 ((tung cap) OR (thong cap)) nhung cong vang ((phan cau) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - thanh ((tung cap) OR (thong cap)) nhung cong vang ((phan cau) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - thanh ((tung cap) OR (thong cap)) nhung cong vang ((phan cau) or (phan cac))*.
