Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
sua nhung » qua nhung, chua nhung, quan nhung
cua nhung » va nhung
cong sat » cong suat, cong san, cong nhat
cong hat » cong nhat, cong chat, cong ha
phan cau » phan dau, phan cac, phan tu

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 thieu xanh - hanh chinh ((sua nhung) OR (cua nhung)) ((cong sat) OR (cong hat)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh chinh ((sua nhung) or (cua nhung)) ((cong sat) OR (cong hat)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh chinh ((sua nhung) or (cua nhung)) ((cong sat) OR (cong hat)) phan cau*.
