As Chongqing people, Chen Changyin and Chen Mahua are natural. There are many Chen Mahua in Ciqikou, Chongqing, and their tastes are different, mainly depending on personal preferences. If it's authentic, I'm still willing to believe in Chen Changyin's twist. On the one hand, it is an old Chongqing brand, on the other hand, it is an intangible cultural heritage of Chongqing.
