Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
hua khong » hoa khong, cua khong, hoac khong
tung hua » trung hoa, cung chua, dung nhua
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
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 xanh) OR (chieu tinh)) - thanh tung hua khong ((cong tan) OR (cong san)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - thanh tung hua khong ((cong tan) or (cong san)) than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - thanh tung hua khong ((cong tan) or (cong san)) than cau*.
