In recent years, prepared dishes have become one of the hottest trends in the catering industry. Restaurants that insist on freshly cooked dishes in stores have become popular, attracting a group of fans.

For chain restaurants with central kitchens, standardized production of pre-prepared dishes can save various costs such as labor and ingredients. Many fast-food restaurants that specialize in take-out are also keen to reduce costs and increase efficiency by purchasing pre- pre-made dishes. Chain catering brands such as Xibei and Meibei Dongpo took the lead in creating high-profile brands through central kitchens.
