Renhuai City is a unique ethnic food. Xueba is purplish red. It can be steamed, boiled, roasted and fried when eaten. It is delicious, with good color, fragrance and taste. It is soft and does not touch teeth. It is said that Xueba was moved to Renhuai in Suzhou during the Wanli period of the Ming Dynasty. When Miao people killed pigs to worship their ancestors, a woman surnamed Tao mistakenly dropped corn flour into the blood of pigs.
