Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
thanh sinh » thanh binh, thanh tinh, thanh vinh
hien xanh » hien hanh, chieu xanh, hien khanh
cua nhung » va nhung
sinh cua » manh cua, dinh cuu, sinh va
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap

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 ((hien xanh) OR (hien nhanh)) - thanh sinh cua nhung ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - thanh sinh cua nhung ((cong dan) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (hien nhanh)) - thanh sinh cua nhung ((cong dan) or (cong tan)) toan cau*.
