Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trung » thanh trung, hanh trang, manh trung
cong quang » luong quang, thong quang, duong quang
trung tan » trung tuan, trung tran, trung tang
cong vang » cong lang, cong ngang, cong san
tan dung » tran dung, tin dung, van dung
toan cau » toan cao, toan ban, toan tap

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)) - hanh trung tan dung ((cong vang) OR (cong quang)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - hanh trung tan dung ((cong vang) OR (cong quang)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - hanh trung tan dung ((cong vang) OR (cong quang)) toan cau*.
