Does the current diet belong to intangible culture?

First of all, we must distinguish the relationship between matter and immateriality. Dietary ingredients or famous dishes, such as pigs, cows, fish or braised pork, grilled steak, sweet and sour mandarin fish, etc., are all materials. Intangible culture refers to the skill of inventing and making famous dishes in China, which represents not only the food itself, but the crystallization of people's wisdom in creating food culture. Take Quanjude Roast Duck as an example. Only the Beijing Roast Duck produced by Quanjude's traditional skills is an intangible cultural heritage. Not all Beijing Roast Duck produced by any store is called intangible culture.
