Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, tran tuan
trung cua » truong cua, trung cap, dung cua
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong van » cong vang, cong san, song van
than cau » toan cau, phan cau, than cap
phan dau » phan tu, hang dau

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 - thanh ((trung cua) OR (trung tuan)) dang cong van ((than cau) OR (phan dau))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((trung cua) or (trung tuan)) dang cong van ((than cau) or (phan dau))*.
