Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thanh phan » thanh pho, thanh san, thanh toan
chua xang » chua nang, chuc nang, chu bang
tien anh » tieng anh, tien manh, tien thanh
dien anh » tieng anh, dien dan
cua xang » cua dang, cua hang, cua lang
phan cau » phan dau, phan cac, phan tu

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: hoc ((tien anh) OR (dien anh)) - canh tranh ((cua xang) OR (chua xang)) cong thanh phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((tien anh) or (dien anh)) - canh tranh ((cua xang) OR (chua xang)) cong thanh phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((tien anh) or (dien anh)) - canh tranh ((cua xang) OR (chua xang)) cong thanh phan cau*.
