Introduction to Luozuo Zhishui: "The river produces pictures, and Luo produces books." "Luo" is a symbol of wisdom, and "water" is one of the important carriers of the Kang family's business. At that time, the Kang family relied on water transportation to start and prosper, and dealt in salt, grain, cotton, and cloth. Therefore, "Luozuo Zhishui" means that the Kang family is wise and sensible, and their business is as long-standing as the Luo River water.
