Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
hoc thieu » toc thieu, hoc hien
nhanh cau » nhanh cay, thanh chau, hang cau
cua dung » cua dang, cua dong, qua dung
cong san » cong tac
nhanh ha » thanh hoa, thanh hai, khanh hoa

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 - nhanh tinh ((cua dung) OR (cua cong)) cong san ((nhanh cau) OR (nhanh ha))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - nhanh tinh ((cua dung) or (cua cong)) cong san ((nhanh cau) OR (nhanh ha))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - nhanh tinh ((cua dung) or (cua cong)) cong san ((nhanh cau) OR (nhanh ha))*.
