Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
canh ban » can ban, canh dan, canh van
cua dang » cua cong, cua ban
cong van » cong vang, song van, cong tan
cong san » cong tac
hanh cay » nhanh cay, hanh cac, hanh cat
ban cua » ban quan

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: hoc ((thieu xanh) OR (chieu xanh)) - canh ban cua dang ((cong van) OR (cong san)) hanh cay~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chieu xanh)) - canh ban cua dang ((cong van) OR (cong san)) hanh cay~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - canh ban cua dang ((cong van) OR (cong san)) hanh cay*.
