Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
lieu tinh » trieu tinh, diep tinh, bien tinh
hang cong » dang cong, hang nong, bang cong
chinh va » chinh ta, chinh tai, hanh va
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cau » toan cau, phan cau, than cap
va hang » van hang, va nang, va lang

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: theo ((chieu xanh) OR (lieu tinh)) - hanh chinh va hang cong tan than cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (lieu tinh)) - hanh chinh va hang cong tan than cau*.
