　　Tuzhen Sweet Potatoes are a specialty of Liangzihu in Ezhou City, Hubei Province.

　　Tuzhen Sweet Potatoes, also known as Tuzhen Hongshao, are produced in Tujianao Town, Liangzihu District, Ezhou City, Hubei Province. Tujianao Town is commonly referred to as Tuzhen. The region features distinct seasons, abundant rainfall, ample sunlight, and a long frost-free period. The soil is mainly red-yellow loam, rich in selenium with organic matter content exceeding 1%, deep soil layers, active topsoil over 60 cm deep, groundwater level below 1 meter, and a soil pH between 5.5 and 7.5, all contributing to the high quality of the sweet potatoes (hongshao) produced here.

　　 Large-scale sweet potato cultivation in the town began last century. It has since gradually developed into an industry, with the town now home to 160 major sweet potato growers and 10 processing enterprises, distributing sweet potato products across the country.
