It must be Chen Changyin. It's printed in people's pockets. Authentic Chen Mahua, looking for Chen Changyin. Anyway, I only bought Chen Changyin's twist and later opened it in Chen Jianping. Ciqikou ancient town's first turning point was Chen Changyin. And now you don't have to buy it at the ciqikou. Online and supermarkets are very convenient. When you want to eat, you can buy some Chen Changyin twist.
