Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
hanh trung » thanh trung, hanh trang, manh trung
trung chua » trung cua, trong chuan, trung ha
hien xanh » hien hanh, chieu xanh, hien khanh
chua bang » chu bang, chua nang, chua xang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, than cap

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)) - hanh trung chua bang ((cong dan) OR (cong tan)) than cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - hanh trung chua bang ((cong dan) or (cong tan)) than cau*.
