Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
hanh tung » thanh tung, manh tung, hanh dung
hanh mang » nhanh mang, hanh trang, nhanh lang
cua trong » cua truong, cua trung, qua trong
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 tung) OR (hanh mang)) cua trong cong san ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh tung) or (hanh mang)) cua trong cong san ((toan cao) or (toan tap))*.
