Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu xanh » chieu xanh, hieu manh, thien anh
vap dung » van dung, ap dung, vat dung
cong dan » cong san, cong tan, huong dan
toan tap » toan ban
toan cao » toan 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: toc thieu xanh - thanh trung ((vap dung) OR (va dung)) cong dan ((toan tap) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc thieu xanh - thanh trung ((vap dung) OR (va dung)) cong dan ((toan tap) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu xanh - thanh trung ((vap dung) OR (va dung)) cong dan ((toan tap) or (toan cao))*".
