Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
hoc chieu » hoc thieu, ho chieu, hoc hien
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than ban » thanh ban, toan ban, than man
ap dung » xay dung

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh tung ((ap dung) OR (van dung)) cong dan than ban~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh tung ((ap dung) OR (van dung)) cong dan than ban*.
