Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tung » thanh cong
xuat duong » xuat thuong, xuat phuong, xuat truong
hoc thieu » toc thieu, hoc hien
mat duong » mai duong, hai duong, van duong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
va dung » van dung, va duong, vat dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu xanh - thanh tung ((((mat duong) OR (xuat duong))) or (va dung)) cong dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh tung ((((mat duong) OR (xuat duong))) OR (va dung)) cong dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh tung ((((mat duong) OR (xuat duong))) or (va dung)) cong dan toan ban*".
