2. Yuanxiao is one of the traditional snacks of Han nationality in China, which belongs to the festival custom. The practice of Yuanxiao is mainly stuffing, which is mixed first, then spread into large round pieces, dried and cut into squares smaller than table tennis. Then put the stuffing into a machine like a big sieve, pour the rice flour on it and "sieve" it. As the fillings collide with each other, the rice sticks to the surface of the fillings and becomes spherical, which becomes Yuanxiao. Yuanxiao is rolled in the north and Tangyuan is wrapped in the south, which are two foods with different practices and tastes.
