Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cao » truong dai
nhung cong » dung cong, thong cong, hang cong
trung cap » trung tam
ho chieu » theo chieu, hoc thieu, doi chieu
van tuan » van quan, van ban, anh tuan
van tan » van ban, van tai, van thanh

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