Perhaps you should try some spelling variations:
dung phuong » dung thuong, bang phuong, dung chung
chieu xanh » chieu sach, chieu sang, chieu tinh
phuong ban » phuong bang, phuong lan, phuong bac
hanh doan » hanh doanh, thanh toan, thinh doan
doan van » doan va, hoang van, luan van
van dung » van dong, xay dung, tin dung
than cao » thai cao, than cap, than sao
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 ((chieu xanh) OR (chinh sach)) - hanh doan van dung phuong ban ((than cao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chinh sach)) - hanh doan van dung phuong ban ((than cao) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chinh sach)) - hanh doan van dung phuong ban ((than cao) OR (toan cao))*.
