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
dung cong » dung trong
tung bay » vung bay, tuong ban, tung dan
bay dung » xay dung, gay dung, ban dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
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: doi ((chieu xanh) OR (chieu tinh)) - thanh tung bay dung cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - thanh tung bay dung cong dan than cau*.
