Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
dinh cua » dinh cuu, sinh cua, tinh cua
cong van » cong vang, song van, cong tan
cong san » cong tac
toan cao » toan ban, toan tap
dinh cu » dinh cuu, dinh chuc, dinh chau

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: hoc chieu xanh - hanh ((dinh cua) OR (dinh cu)) hang ((cong van) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh ((dinh cua) or (dinh cu)) hang ((cong van) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh ((dinh cua) or (dinh cu)) hang ((cong van) OR (cong san)) toan cao*.
