Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thuc chung » thuc cung, thuc nhung, thung chung
thanh pham » thanh phan, thanh pho, thanh hai
hoc chieu » hoc thieu, ho chieu, hoc hien
thuc hung » thuc nhung, thuc dung, thuc cung
than phan » thanh phan, toan phan, thanh nhan

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 - tinh toan ((thuc hung) OR (thuc chung)) cong ((than phan) OR (thanh pham)) cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - tinh toan ((thuc hung) OR (thuc chung)) cong ((than phan) or (thanh pham)) cac~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - tinh toan ((thuc hung) OR (thuc chung)) cong ((than phan) or (thanh pham)) cac*.
