Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
nhanh mang » nhanh lang, hanh mang, nhanh quang
dong thanh » truong thanh
hang dong » hang nong, hang cong, hanh dong
mang cua » manh cua, dung cua, ban cua
cua hang » cua dang, cua nhung, cua cong
thuc dan » thuc hanh, thuc vat

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) OR (chieu sang)) - nhanh mang cua hang dong thanh ((thuc dan) OR (hoc dan))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - nhanh mang cua hang dong thanh ((thuc dan) OR (hoc dan))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - nhanh mang cua hang dong thanh ((thuc dan) OR (hoc dan))*.
