Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, hanh trinh, minh trang
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
than cao » toan cao, than cap, than sao
thai cao » tai cao, thoai cac, thuat cao
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: ho chieu xanh - ((hanh trang) OR (canh tranh)) va dung cong dan ((than cao) OR (thai cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trang) or (canh tranh)) va dung cong dan ((than cao) OR (thai cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trang) or (canh tranh)) va dung cong dan ((than cao) OR (thai cao))*.
