Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thuc phung » thuc chung, thuc nhung, thu phuong
phung cong » nhung cong, phong cong, nhung chong
hoc chieu » hoc thieu, ho chieu, hoc hien
toan thuc » toan hoc, dan thuc, nhan thuc
cong than » cong thanh, cong thang, cong tan
phan cach » nhan cach, phap cach, phong cach
phan tach » phan tich, phan thanh, phan tap
phan cac » nhan cach, phan dau, phan lap

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