Perhaps you should try some spelling variations:
chung cuong » hung cuong, chuong duong, hung vuong
chieu xanh » chieu sang, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
chieu tinh » trieu tinh, lieu tinh, chau tinh
thuc chung » thuc cung, thuc nhung, thung chung
cuong than » cung than, muong thanh, luong thanh
toan thuc » toan hoc, dan thuc, nhan thuc
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 xanh) OR (chieu sach))) or (chieu tinh)) - tinh toan thuc chung cuong than phan cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((chieu xanh) OR (chieu sach))) OR (chieu tinh)) - tinh toan thuc chung cuong than phan cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((chieu xanh) OR (chieu sach))) or (chieu tinh)) - tinh toan thuc chung cuong than phan cac".
• Adding a wildcard symbol may retrieve word variants: hoc ((((chieu xanh) OR (chieu sach))) or (chieu tinh)) - tinh toan thuc chung cuong than phan cac*.
