Huaifu healthy duck is produced in Jiaozuo, the origin of the "Four Great Huai Medicines": it faces the majestic Taihang Mountain in the north and the flat river shaped like a horn in the south. Rich nutrients in different geological conditions in the upper reaches of the Yellow River are collected, and a large number of trace elements infiltrated from the karst landform of Taihang Mountain are absorbed. Coupled with the protection of Taihang Mountain, the yang of the mountain and the yin of the water are integrated, forming a climate environment of "no drought in spring, no heat in summer, no waterlogging in autumn and no cold in winter". It is the unique soil and water climate environment that gave birth to the "Four Great Huai Medicines". Healthy duck breeding in Huaifu adopts local natural crops as feed raw materials, which is original ecology. The taste is sweet, neither cold nor hot, neither damp nor dry. It can strengthen the spleen, tonify deficiency, benefit the heart and soothe the nerves, and has high health care value after long-term consumption. Especially for people who are weak and have indigestion, it is a rare tonic.
