Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
qua trong » quan trong, qua trinh, qua song
nhan cach » phan cac
tung qua » dung qua, tuong quan, trung quan
cong dan » cong san, cong tan, huong dan
cong tac » cong ty
than cau » toan cau, phan cau, than cap

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 - thanh tung qua trong ((cong dan) OR (cong tac)) ((than cau) OR (nhan cach))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tung qua trong ((cong dan) or (cong tac)) ((than cau) or (nhan cach))*.
