According to reports, the food culture in Langzhong has a long history, which is composed of the food cultures of Hui, Han and Man, among which the most famous are Baoning vinegar, white sugar steamed buns, hot cold noodles and Zhang Fei beef. It is one of the traditional delicacies of Langzhong Beef Processing Factory in Sichuan, with good color, fragrance and taste. As early as 1940s, this kind of beef jerky won the Silver Award of High-quality Products of Chengdu Industrial Association. Because the dried meat is not hard, moist but not soft, it is black outside and red inside, so it is called "Zhang Fei beef". Cut its horizontal grid, gently tear the cut surface, such as silver pine needles, chew it carefully, and its taste is endless. A plate of Zhang Fei beef we ordered immediately bottomed out. Lantian, the housekeeper, quickly asked the store to bring another plate so that everyone could have another good meal.

There are many kinds of flavor snacks in Langzhong, most of which have superb cooking skills. From the Han and Tang Dynasties to the Ming and Qing Dynasties, Langzhong people went to Beijing as officials, and the prince appointed them to Langzhong, which spread the food culture of the capital and the imperial court to Langzhong. It is said that it is precisely because of the exchange and integration of Manchu food culture and Han food culture that Langzhong had a "Manchu-Chinese banquet". Islam was introduced into Langzhong in the early Qing Dynasty, which brought the Hui people's food culture and formed a variety of snacks. Tongjiqu beef noodles, spindle guokui, sugar steamed buns, braised beef in hot pot, roasted meat in hot pot, bean jelly in northern Sichuan, hot cold noodles, etc. , gradually became famous in Sichuan.
