Perhaps you should try some spelling variations:
truong thanh » truong trung, truong thpt
truong chung » truong trung
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong san, cong thanh
toan ban » van ban

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