Chengshi brewing began in 2015, using a mixed brewing method that involves secondary fermentation of various flower, fruit, milk tea, and beer, selecting the most reasonable and flavorful combination for mass production. It adopts a membership system and directly cooperates with bars for lower prices and higher quality. At the same time, it also accepts small-scale customized development by bars to achieve one city, one flavor, and make the cooperating bars more competitive. 笔
