Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh trang » thanh trung, canh tranh, hanh trinh
nong nganh » trong nganh, duong nganh, cong ngang
nganh toan » nganh thanh, thanh toan, manh toan
hanh mang » nhanh mang, nhanh lang, thanh hang
cong nong » cong dong, cong cong, cong trong
toan chau » toan cau, tran chau, toan chay

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 sang)) - ((hanh mang) OR (hanh trang)) cua cong nong nganh toan chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - ((hanh mang) or (hanh trang)) cua cong nong nganh toan chau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - ((hanh mang) or (hanh trang)) cua cong nong nganh toan chau*.
