Food is not only food to meet physiological needs, but also the embodiment of culture, art and socialization. A good meal can be an appreciation of cooking, a taste of ingredients and an experience of food culture. It can be a way to relax and enjoy, so that people can temporarily get out of their busy lives and immerse themselves in the world of food. Food is also a social medium. People can enhance friendship, strengthen family relationships or expand interpersonal networks by tasting food together.
