Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
trinh vat » trinh van, trinh luat, sinh vat
cong dang » cong dong, cong dan, cong dung
dang hung » dang quang, manh hung, dang cong
trinh va » trinh van, trinh ve, trinh vi
hung cau » nhung cau, huong cau, hang cau

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: theo ((chieu xanh) OR (chieu sach)) - hanh ((trinh va) OR (trinh vat)) nhung cong dang hung cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - hanh ((trinh va) or (trinh vat)) nhung cong dang hung cau*.
