I think there are two reasons. Let's see if this is the reason.

First, exploring food is a very important part of travel, and food can attract more attention. Since ancient times, food is the most important thing for the people, and the food culture has a long history. The eight major cuisines have their own characteristics, and each place has its own unique side. For example, stew is the main food in the northeast, pasta, beef and mutton are the main food in the northwest, and rice and spicy food are the main food in the south. This is only a superficial generalization, and there are refinements in various places. In addition, with the great flow of food in the country, a large number of innovative foods have emerged, and more and more people do not go to scenic spots to eat food exclusively.

Second, it is less difficult to eat and shoot than to visit scenic spots. For example, wow, what's in Balabala? Take a bite, talk about whether it's delicious or not, and play it for millions, saving time and effort. They are all trying to make money to eat, so why not? Some anchors can also get various sponsorships, and their value will increase with the fans, and then the appearance fee and delivery fee will increase.
