Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
cuong than » cung than, muong thanh, luong thanh
hoc chieu » hoc thieu, ho chieu, hoc hien
thuc hung » thuc chung, thuc nhung, thuc cung
thuc dung » thuoc dung, tuc dung, thuat dung
thuy dung » thuy duong, thuoc dung, huy duong
than phan » thanh phan, toan phan, thanh pham
phan cac » nhan cach, phan dau, phan lap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu tinh - tinh toan ((thuc hung) or (((thuc dung) OR (thuy dung)))) cuong than phan cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - tinh toan ((thuc hung) OR (((thuc dung) OR (thuy dung)))) cuong than phan cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - tinh toan ((thuc hung) or (((thuc dung) OR (thuy dung)))) cuong than phan cac".
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - tinh toan ((thuc hung) or (((thuc dung) OR (thuy dung)))) cuong than phan cac*.
