Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thieu xanh » thien anh, thien danh
thanh tung » thanh cong
hieu manh » hieu nganh, dieu hanh, hien hanh
dung cong » dung trong
tung vat » dung vat, tang vat, tung va
vat dung » van dung, va dung, viet dung
cong tan » cong tac, cong san, cong thanh
tan phan » toan phan, than phan, van phan

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: toc ((((thieu xanh) OR (hieu manh))) OR (chieu xanh)) - thanh tung vat dung cong tan phan tu~.
• Adding a wildcard symbol may retrieve word variants: toc ((((thieu xanh) or (hieu manh))) or (chieu xanh)) - thanh tung vat dung cong tan phan tu*.
