In terms of taste, Ziyan Baiwei Chicken and Couple's Lung Slices have their own advantages. Just from Ziyan Baiwei Chicken and Couple's Lung Slices, Baiwei Chicken is braised, and Couple's Lung Slices is a compound of braised and cold. Since it is a signature dish, we can also see the characteristics of the two brands: Ziyan Baiwei Chicken and Couple Lung Slices: Ziyan Baiwei Chicken tends to be braised, while Couple Lung Slices are both braised and cold. However, Ziyan Baiwei chicken is well done in the north, while husband and wife lung slices are well done in Sichuan, so there are still some regional differences in taste, and it is not possible to judge whether Ziyan Baiwei chicken is good or husband and wife lung slices are good. However, from my personal point of view, the husband and wife lung films are still slightly better. First of all, it is not because I am from Sichuan. Ziyan Baiwei Chicken has been operating in Nanjing since 1996, but it didn't develop in Chengdu market until 2118. It is also because the high-profile appearance of Ziyan Baiwei Chicken has attracted the attention of Chengdu people: 51 stores were opened in Chengdu overnight. From this point, we can see a clue that Ziyan Baiwei Chicken has a foothold in Chengdu not by its taste, but by virtue of its strong financial strength. Ziyan Baiwei Chicken has achieved the current mode, and its taste has been standardized. In terms of workmanship, it is craftsman-like, but not master-level; Therefore, Ziyan Baiwei Chicken has never made its mark in the national food exhibition, which is also the reason. The couple's lung slices have been able to represent the nation and show the essence of a traditional food of our nation to the world.
