The battle between coffee merchants in Shanghai is becoming more and more fierce. Kashijia competes with Starbucks.

In Shanghai today, the smell of coffee is floating in the air. This international metropolis, with a resident population of 25 million, not only has more than 4000 cafes, large and small, but more importantly, chain fast food restaurants and convenience stores have also fully joined the ranks of freshly ground coffee this winter, striving to get a share of the growing coffee consumption market. Behind the competitive layout is the rapid expansion of China's coffee market.
