It is more profitable to sell rice noodles than fried skewers. Rice rolls are made by grinding and steaming ordinary rice or early rice, and then adding fillings and soups. The production process is simple, the equipment is easy to operate, the cost is low, and the profits are considerable. There are many places that decorate rice roll shops in a relatively high-end style. If the rice rolls are sold at a high price, the profit will be even greater if the location is well chosen.
