First of all, the price. Compared with KFC and McDonald's, the price of Yonghe Soymilk is obviously closer to the public, because the customers of Yonghe Soymilk are mainly middle-aged people.

The second is speed. The ordering speed and serving speed of Yonghe Soymilk are not slow, and people usually leave after eating in Yonghe Soymilk, instead of doing it for a long time like in KFC or McDonald's, thus keeping Yonghe Soymilk from being overcrowded. This will enable customers to find seats in the first time, instead of looking for seats back and forth like KFC and McDonald's.

Then, it was mentioned before that the customers of Yonghe Soymilk are mainly middle-aged people. As far as their taste is concerned, even though the food in Yonghe Soymilk is not as delicious as the food at home or the dishes in big hotels, it is obviously more popular with them as a Chinese fast food.

So, even though Yonghe Soymilk is not very delicious, it can still stand in front of KFC and McDonald's.
