Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
quang cao » nang cao, quang nam, quang cua
trung cap » truong cao, trung tam
ho chieu » theo chieu, hoc thieu, doi chieu
cong van » cong vang, song van, cong tan
cong san » cong tac
tan cau » toan cau, van cau, tan ca

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 ((quang cao) OR (trung cap)) nhung ((cong van) OR (cong san)) tan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((quang cao) or (trung cap)) nhung ((cong van) OR (cong san)) tan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((quang cao) or (trung cap)) nhung ((cong van) OR (cong san)) tan cau*.
