Perhaps you should try some spelling variations:
nho chieu » ho chieu, theo chieu, nhat chieu
dang cong » dung cong
cong tinh » cong trinh, cong vinh, long tinh
nho hieu » nha hieu, nho sieu, nhu hieu
chinh va » chinh ta, chinh tai, hanh va
toan cau » toan cao, toan ban, toan tap
va dang » van dang, va nang, va lang

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: ((nho chieu) OR (nho hieu)) sang - hanh chinh va dang cong tinh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((nho chieu) or (nho hieu)) sang - hanh chinh va dang cong tinh toan cau*.
