Cao Zhuang Village in Anping County is located on the north bank of Hutuo River, where white yam has a long history of cultivation. At the end of the Qing Dynasty, farmers in this village had the habit of planting vegetables and going to the market to sell vegetables. At that time, farmers planted one or two or four or five beds of white yam as a seasonal vegetable, and sold it in rural markets after harvest or presented it as a tonic for nourishing the body and giving it to confinement (having children) and sick relatives and friends. Because of its low output, it has become a rare treasure.

In 1963, the Hutuo River was flooded, and there was a north-south horizontal canal in the cultivated land of Cao Zhuang Village. Because there was a sluice on the north dike of Hutuo River to stop the flood, the sediment was deposited on the cultivated land for more than one meter, which caused the cultivated land in this village to be sandy soil on the top and fertile soil on the bottom, which was very suitable for the growth of white yam. After many years, farmers in this village have cultivated high-quality Baishan drugs commonly known as "Xiaobaizui".

since the implementation of the production responsibility system, farmers have the right to plant freely, and farmers have begun to plant Baishan medicine from vegetable garden to field, and the planting area has expanded year by year, reaching more than 5 mu in this village alone. The cultivation of white yam has gradually become an industry, and then radiated to the surrounding villages. The planting area has reached more than 2, mu and the output can reach 5 million kilograms.

In recent years, the reputation of Cao Zhuang White Yam is far-reaching, and local silk screen merchants are highly praised as gifts for Anping specialty. Now "Xiaobaizui" Baishan medicine has been exported to Beijing, Tianjin, Guangzhou, Shanghai and other large and medium-sized cities, and has been favored by local citizens and become a delicious food on people's tables.

in order to make the white yam industry bigger and stronger, and form a coordinated process of planting, management, storage, transportation and sales, in June 213, the village established the "Cao Zhuang White Yam Cooperative of Anping County", registered the brand of "Caojiazhuang" white yam, and uniformly printed the packing boxes and gift boxes, which laid a solid foundation for the scale and level. Cao Zhuang Village will surely become the distribution center and sales center of "Xiaobaizui" white yam. There is a large supply of white yam. Welcome new and old customers to negotiate and purchase.

Anping Chuangjia White Yam Planting Cooperative is a standardized enterprise integrating development, planting, processing and sales. With a complete and scientific quality management system, the company's integrity, strength and product quality are recognized by the industry.

White yam is rich in mucus juice, choline, protein, polyphenol oxidase, vitamin C, mannan, phytic acid, 16 kinds of amino acids, allantoin and 3,4-dihydroxyphenylethylamine, etc. These are all important nourishing ingredients, which can tonify the spleen and stomach. Therefore, white yam is not only an important tonic food, but also an important medicinal material, so it has been "yam yam, a medicine in the mountains" since ancient times.
