Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
tong cong » trong cong, cong cong, dung cong
cua tong » cua cong, cua dong, cua nong
cong san » cong tac
toan cao » toan ban
toan tap » toan ban

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: hoc chieu xanh - ((hanh tang) OR (hanh mang)) cua tong cong san ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((hanh tang) OR (hanh mang)) cua tong cong san ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh tang) OR (hanh mang)) cua tong cong san ((toan cao) or (toan tap))*.
