Catering has become a take-away form, just like Taobao. It can be said that it will be more and more perfect, but at present, take-away is only for local people or the service distance is close. To be like Taobao, all over the country, all-round, I'm afraid it can only be aimed at the supply of some raw materials or the low shelf life requirements of food. After all, food requires hygiene and freshness, and the time limit and storage requirements are high. So it is too expensive to make catering like Taobao, and there are great difficulties in logistics and transportation, so it is not feasible at present.
