Perhaps you should try some spelling variations:
manh truong » manh trung, manh tuong, anh truong
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cao » truong dai
hien xanh » hien hanh, hien nhanh, hien khanh
dung cong » dung trong
cao dung » cao dang, cao dong, cao ung
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao
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: hoc ((hien xanh) OR (chieu xanh)) - manh truong cao dung cong dan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - manh truong cao dung cong dan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - manh truong cao dung cong dan ((toan tai) or (toan ban))*.
