Perhaps you should try some spelling variations:
thuong hung » thuong dung, thuong phuong, truong chung
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh nung » thanh tung, thanh hung, thanh dung
nung cao » nang cao, nhung cau, quang cao
van phan » van phong, van thanh, luan phan
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: theo ((chieu xanh) OR (chieu sang)) - thanh nung cao ((thuong hung) OR (cong dong)) van phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - thanh nung cao ((thuong hung) or (cong dong)) van phan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - thanh nung cao ((thuong hung) or (cong dong)) van phan cau*.
