Perhaps you should try some spelling variations:
thieu manh » tien manh, trieu minh, chieu xanh
nguong dan » huong dan
hieu manh » chieu xanh, hieu nganh, dieu hanh
canh manh » lanh manh, canh tranh, cach mang
manh cua » doanh cua, ban cua
cua hang » cua dang, cua nhung, cua cong
nong dan » cong dan, nong san, huong dan
phan cau » phan dau, phan cac, phan tu

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 manh) OR (hieu manh)) - canh manh cua hang ((nong dan) OR (nguong dan)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) or (hieu manh)) - canh manh cua hang ((nong dan) OR (nguong dan)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) or (hieu manh)) - canh manh cua hang ((nong dan) OR (nguong dan)) phan cau*.
