Perhaps you should try some spelling variations:
chong cong » cong cong, thong cong, cuong cong
cong thanh » dong thanh, cong trinh, cong tan
thanh than » thanh thanh, thanh thang, thanh toan
mot chieu » doi chieu
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
ho chieu » theo chieu, hoc thieu, doi chieu
than cau » toan cau, phan cau, than cap

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) OR (mot chieu)) xanh - thanh ((trung cua) OR (trung cap)) chong cong thanh than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) xanh - thanh ((trung cua) OR (trung cap)) chong cong thanh than cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) xanh - thanh ((trung cua) OR (trung cap)) chong cong thanh than cau*.
