At first, the "seven pieces of mountain treasures" called by the villagers included seven kinds of mountain products: bear's paw, elephant trunk, deer tendon, hump, bird's nest, dictyophora indusiata and Hericium erinaceus.

later, there were "eight treasures of animals", namely bear's paw, elephant trunk, deer tendon, hump, scarlet lip, deer tail, monkey brain, leopard embryo and "four treasures of plants", namely dictyophora, bird's nest, mushrooms and tremella.

With the improvement of people's awareness of ecological environment protection, the so-called "mountain delicacies" at present refer to mountain products, such as mushrooms, dictyophora, Pleurotus ostreatus, Tricholoma, pine nuts, chestnuts, torreya grandis, ginkgo, walnuts and bamboo shoots, which are produced in mountainous areas and cultivated by mountain people under natural ecological environment.

people have always regarded "delicacies and delicacies" as delicacies, and divided them into eight treasures. ?

Bazhen is the name given to eight kinds of precious cooking materials and foods made from them by China catering industry, with different contents in history. It first appeared in the Zhou Dynasty, and there is a saying that "eight things are used sparingly". After the Ming and Qing Dynasties, seafood gradually became a delicacy, appearing in eight treasures of the sea and eight treasures of the mountains. In modern times, people divide the precious raw materials of delicacies into upper, middle and lower treasures. The top eight treasures are: raccoon lip, bird's nest, hump, bear's paw, deer tendon, Hericium erinaceus, leopard fetus and toad; Eight treasures: shark's fin, civet, radix aconiti, tripe, turtle skirt, fish lips and shad; The next eight treasures: Sichuan bamboo shoots, tremella, mushrooms, Hericium erinaceus, scallops, fish bones, fish intestines and mullet eggs. ?

in addition, such as fish skin, abalone, flying fish, etc. are also rare delicacies. ?

In fact, "delicacies and delicacies" have no particularly high nutritional value, no matter the proportion of amino acids, vitamins, inorganic salts or trace elements. For example, bird's nest, which is cemented by half-flowers mixed with saliva in Jin Siyan, has a sugar content of 31.55%, which is not as good as the same amount of sugar cereals; Its protein content is 49.455, which is not as good as the same amount of crab meat, its fat content is 1.3%, and it is also different from the same amount of meat, soybeans, etc., and its wide substance content is milk. In short, there is no scientific data to prove that "delicacies and seafood" are usually dried in the sun, baked, dehydrated or pickled, during which the nutritional components are constantly destroyed. Therefore, the blind pursuit of "delicacies" is really not worth the candle.
