Dou Qian Qian

Bean Qian Qian boiled white beans half-cooked, then put them on smooth bluestone or steel blocks, and pounded them into small discs with a small hammer, which looked like copper coins, hence the name Qian Qian. When cooking small rice, put it into the pot at the same time as rice, or add it to the noodle soup, which has a special flavor.
