The main reason is that people in these cities are busier and have a better sense of time, so they tend to choose convenient take-out food instead of cooking or eating out.

The number of delivery drivers is quite large in first - and second-tier cities, and has a trend of gradually covering third - and fourth-tier cities. Also, the food is delivered to more places, from residences and office buildings to hotels and hospitals.

A user on microblog Sina Weibo said, " How I envy them! I want to quit my job and be a food delivery worker", but some held a different view, that the delivery couriers work so hard to deliver packages every day.
