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
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
than ban » thanh ban, toan ban, nhuan ban
than man » than ma, thanh san, tran manh
tung ap » tang ap, tung dan, tung bay
ap dung » xay dung, van 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 cong dan ((than ban) OR (than man))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - thanh tung ap dung cong dan ((than ban) OR (than man))*.
