What is bird's nest made of?

"Bird's nest" means eating bird's nest. Bird's Nest is an edible bird's nest formed by colloidal saliva secreted by Jin Siyan, which is unique to Southeast Asia. At the earliest time, a large number of people in Southeast Asia went to caves to collect bird's nest, which was not only extremely dangerous, but also looted nature after picking caves. On the cliffs of several small islands in Thailand, many rotten bamboo ladders lead to caves once rich in bird's nest. Now these caves are abandoned, and Yaner is gone. With the increasing calls for protecting nature, the Yanwu invented by Indonesian Chinese came into being. The structure of these swallow houses is no different from that of ordinary houses, but raising swallows is not raising birds. Swallows are still wild and feed on their own. The house is only used to attract swallows to live together, so that swallows can nest in the house and collect a large number of bird's nests. Yanwu, the boss of Bird's Nest Factory, believes in Buddhism, loves Ru Yan as much as his life, and firmly believes that life is rare, Buddhism stinks, and bird's nest is hard to build. The bird's nest in the Swallow House in the nest factory cannot be picked until the swallows hatch on 18-24 and fly in 45 days. Jin Siyan went back to the house and built a new nest, which was handed down from generation to generation. Blood swallow is not the result of Jin Siyan vomiting blood, because red hemoglobin will only be oxidized to dark brown methemoglobin. Blood swallow is related to eating seaweed and insect food along the coast of Jin Siyan, which contains more minerals. Because blood swallows are scarce, the price is also high. The classification of bird's nest is as follows: 1. According to the picking location, it is divided into house swallow and cave swallow. Cave swallows were picked in caves, but now they are gradually replaced by domestic swallows because of the scarcity of production and the growing voice of environmental protection. The swallow was picked at home. Jin Siyan is still wild. It goes out for food in the morning and comes back at night. 2. According to the edible degree of bird's nest, it is divided into Jin Siyan, Cao Yan and Mao Yan. Jin Siyan is the edible bird's nest after cleaning. Caoyan and Maoyan are non-Swift nests in Jin Siyan, and their bird's nests have few contents and cannot be eaten. Wool bird's nest is an unwashed bird's nest, which can be eaten after washing. 3. According to the shape of bird's nest, it can be divided into swallow lanterns, strips, pieces, cakes, horns and nets. The first three can be classified according to the degree of damage after picking and transportation. Yan cake is made of processed and pressed. Yanjiao is the bottom adhesive part of the nest on the wall of Jin Siyan. It tastes delicious. White swallow net is a fine net that supports eggs and Xiaoyan in the middle of bird's nest, and its taste is delicate and smooth. 4. In addition, they are divided into Bai Yan, Blood Swallow and Yellow Swallow by color. As for Yan Guan and Gong Yan, they both mentioned the perfect first-born bird's nest.
