In the Qing Dynasty, Huangshan Biscuits were praised by the Emperor Qianlong for “Huangyin Biscuits”. For the first time, Qianlong went down to the south of the Yangtze River, and was received by Zhang Jiangchun, the head of the “Two Huai Ba Da Shang Shang”. The first tea that Jiang Chun took over was a group of chefs composed of Huizhou team. According to his carefully designed and collectively developed biscuits, the outer layer is crispy, the inside is moist and delicious, and the chewing is delicious and delicious. Qian Longdun feels comfortable and refreshed, and his spirit is multiplied. He is also eager to give the name "Huangyin Spicy Biscuits", which means that Qianlong’s love for sesame seeds is comparable to that of the emperor, giving it the most noble reward.

The main theme of Chaogang Huangshan Biscuits launched by Hu Xingtang is “good biscuits, nine layers of skin, three good stuffing”. The skin needs nine layers – many are hard, less are cotton, and the nine layers are crisp. On the basis of traditional skills, Hu Xingtang innovated “nine-layer pastry technology” and controlled “four key processes” – instant noodles: soaking for 6 hours; kneading noodles: state can be ramen; clams: 9 layers of crisps; Baking: first cool down after high temperature. Stuffing should be three good - put "good meat, vegetables, oil" three levels: meat - pork ridge meat: moisturize with meat - only choose the best fat, the oil just does not spill oil, to ensure that the fragrance is not greasy . Dish - mustard greens: seasoned with vegetables - only the meat is full of mustard, combined with traditional and modern techniques, washed, baked, cut, marinated for more than a year and a half, reduced saltiness, salty flavor. Oil - pressed vegetable oil: scented with oil - only choose the traditional physical pressing, natural and no added vegetable oil, and then add the odor to the odor to ensure the oil is pure and mellow. During the Daoguang Period of Anhui Huangshan Chaogang Food Co., Ltd., Hu’s ancestor Hu Fusheng chose the golden city mouth of Tunxi Old Street to create the “Huxingtang” cake shop. Its secret Huangshan biscuits are “heavy”, “fresh” and “heavy”. The three characteristics of "Fire Power" are well-known in the world, and they are widely spread across Suzhou and Hangzhou. During the years of the Republic of China, Hu Xingtang’s centuries-old foundation was burned by the chaos, and it was no longer brilliant. In order to revitalize the ancestral industry, in 1992, Hu Shichuan, Mr. Hu Guoxun, Zun Zun Zu Xun, determined to develop Hu's pastry business, established Huangshan Chaogang Food Co., Ltd., and revived the “Hu Xingtang” 100-year-old in Huangshan. It has now developed into a modern baking enterprise with more than 70 chain operations. The sesame cake produced by it is baked along the ancestral techniques and supplemented by modern techniques. It is the leader of the Huangshan sesame cake. Refined pastry cakes, Huangshan bean curd and many other Huizhou famous spots are all very popular and well received by Chinese and foreign tourists.
