Perhaps you should try some spelling variations:
thanh thang » nhanh thang, thanh thanh, thanh hang
trong trinh » trong tinh, trang trinh, trong thinh
chieu xanh » chieu sach, chieu sang, chieu tinh
trinh toan » tinh toan, thanh toan, trinh han
chuc danh » chuc nganh, chuc nang, thuc dan
thang va » hang va, trang va, thong va
toan tap » toan ban
va dung » van dung, va duong, vat dung

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: theo ((((chuc danh) OR (thuc hanh))) OR (chieu xanh)) - thanh thang va dung trong trinh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chuc danh) OR (thuc hanh))) or (chieu xanh)) - thanh thang va dung trong trinh toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chuc danh) OR (thuc hanh))) or (chieu xanh)) - thanh thang va dung trong trinh toan tap*.
