The most authentic one must be Chen Changyin's twist. Maybe foreigners will be more ignorant when they come to Ciqikou. Why are there so many ancient towns of Chenmahua? Actually, you don't need to see anything else. Find a Chen Changyin Mahua. Chen Changyin's grandparents were selling twist from the beginning, and people at Ciqikou used to call him Mr. Chen, so they later called him Mr. Chen Twist. Chen Changyin used to fry twist in porcelain mouth, but later business was booming, and more and more "aged twist" appeared in porcelain mouth.
