All belong to biscuits and snacks. One difference is that they have different tastes. Fresh onion crisp is an old-fashioned snack with onion flavor, and it is a casual breakfast in bulk. There are several brands, among which Sanniu is one. It comes from the magical delicacy of Sanniu, crisp and sweet, and is a good choice for breakfast with milk. Because the old biscuits have evergreen patterns on them, evergreen has become the general name of this kind of scallion cake.
