Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhanh dong » hanh dong, nhanh chong, anh dong
cong thanh » dong thanh, cong trinh, cong tan
ho chieu » theo chieu, hoc thieu, doi chieu
dong cua » dung cua, cong cua, huong cua
vat cong » bat cong, sat cong, vat con
toan cau » toan cao, toan tai
toan ban » van 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: ho chieu xanh - nhanh dong cua vat cong thanh ((((toan cau) OR (toan ban))) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - nhanh dong cua vat cong thanh ((((toan cau) or (toan ban))) or (toan tap))*.
