Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, hien khanh
hanh nang » anh nang, ganh nang, hanh mang
cao nhung » cho nhung, cam nhung, cao chung
cong hai » cong thai, cong ha, hoang hai
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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)) - hanh nang cao nhung cong hai ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (chieu xanh)) - hanh nang cao nhung cong hai ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (chieu xanh)) - hanh nang cao nhung cong hai ((toan cau) OR (toan tap))*.
