Perhaps you should try some spelling variations:
thanh trung » thanh tung
tien thanh » tien thinh, tran thanh, den thanh
trung tran » trung tuan, trung thanh, trung tam
hien xanh » hien hanh, hien nhanh, chieu xanh
thong dan » thong van, tuong dan, thong den
tran han » tran hanh, tran hoan, tran nhan
cong dan » cong san, cong tan, huong dan
can cau » van cau, ban cau, ca cau

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 (tien thanh)) - thanh trung tran han ((cong dan) OR (thong dan)) can cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (tien thanh)) - thanh trung tran han ((cong dan) or (thong dan)) can cau*.
