Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu tinh » trieu tinh, chieu tinh, thien tinh
hoc thieu » toc thieu, hoc hien
va tuong » va thuong, va thong, xa truong
vat dung » van dung, va dung, viet dung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
va dong » van dong, ha dong, xa dong

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 tinh - thanh trung ((((va dong) OR (va tuong))) OR (vat dung)) cong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - thanh trung ((((va dong) or (va tuong))) or (vat dung)) cong dan toan ban*.
