"Jin Siyan" nests three times a year, and the first nest is thick and white. Because Jin Siyan has a long winter and has a long time to recuperate, it stores enough nutrients in its body, and the quality of saliva is better, so the nest built is better and thicker, and it is shaped like a lamp, so it is named Yanzhan, which is the best in bird's nest. In June, Jin Siyan built a nest again. Due to the short distance, his physique could not be fully recovered, so the quality of the nest was poor, and it was thin and hairy, which was obviously slightly worse than the first time. In September, Jin Siyan made a nest for the third time. It was said that because Jin Siyan was approaching the production period, and time was pressing, the physical strength and saliva could not be fully supplemented, and the young swallows needed to be fed urgently. Therefore, the third nest was definitely worse than the previous two times. Therefore, it was not credible to choose more feathers and impurities to build liquid, and even the blood was spit out to become blood swallows. There is a kind of "blood swallow" in the bird's nest. Many people mistakenly think that it is called "blood swallow" because the swallow lacks saliva and even spits out blood to build a nest.
Blood swallows are mainly produced in Luolanyan Mountain, Kangshi Mountain, Songkhla Mountain and other places in Thailand, which is not formed by the blood vomited by swallows as legend has it. According to the data, the quality of blood swallows is actually better than that of Bai Yan, and the aroma and ingredients obtained by soaking are not as good as those of white bird's nest. Blood swallows are only precious in recent years.
Another is called "Bai Yan", which is mostly produced in Indonesia, and another is called "Maoyan", which is mostly produced in Brunei and Borneo. This kind of Maoyan is thin, dark and full of feathers and impurities. It is mainly built by a kind of "Jin Siyan with gray waist", and others with too many impurities and feathers are collectively called Maoyan.
Senior Dr. Jiang Runxiang analyzed that bird's nest can promote cell division (not cancer cells), stimulate lymph gland cells, promote kidney development, have immune and antibacterial effects, and maintain youthful vitality. Bird's nest has the same effect regardless of its origin and grade. Bird's nest is best stewed with peeled old chicken. Bird's nest also has "domestic swallow" and "house swallow", which are made by living in ancient big houses and nesting. Bird's nest was only used as medicine in the Yuan Dynasty, and it can keep young through the skin. Bird's nest is rich in nutrients such as protein, carbohydrates, ash, phosphorus, calcium, iron and potassium, and it is the best for nourishing people.

China people think the most beautiful food often has aesthetic characteristics of strong imagination. The collection and cultivation of this feature is not through investigation, anatomy, observation and experiment, but all from imagination and speculation. And the most "beautiful" food, of course, is the four kinds in the eyes of China people: bird's nest, bear's paw, shark's fin and abalone. Here, one by one, let's take a look at how complementary they are, how embarrassing they are, and how valuable they are.
What is bird's nest? All the data claim that it is "a tonic with high nutritional value", and even university researchers and chemists have issued certificates saying that it "contains 49.9% of protein, contains a lot of bioactive protein molecules, and contains a lot of fat, phosphorus, sulfur, calcium, potassium and other ingredients, which has the function of nourishing yin and rejuvenating the human body." Zhao Xuemin's Compendium of Materia Medica in the Qing Dynasty simply said: "Bird's nest can nourish lung yin, eliminate phlegm and relieve cough, and tonify it to clear it up, which is a holy medicine for conditioning deficiency and fatigue. All diseases due to lung deficiency can not clear the disciples, and they can be treated with this. " Experts in the new era have found that bird's nest contains epidermal growth factor and auxiliary cell division components, which are helpful to stimulate cell growth and reproduction, and promote human tissue growth, cell regeneration and immune function caused by cells. In addition, bird's nest also contains a lot of mucin, glycoprotein, calcium, phosphorus and other natural nutrients, which have the effects of moistening lung dryness, nourishing kidney yin and tonifying deficiency, can enhance the body's resistance to diseases and help to resist colds, coughs and colds. Therefore, it is the most effective for smokers and people suffering from respiratory diseases, and it is a pure and noble natural health care product.
Is there really any evidence? In fact, there is no such grand "theory", probably because it is difficult and rare. The bird's nest is Jin Siyan's nest. Every year1February to March, Jin Siyan flies from Siberia and other places to natural caves along the tropical coast to breed, so it is necessary to build a nest. At this time, it became a good opportunity for collectors to destroy people's nests. Collecting bird's nest on the rock climbing wall is very hard and dangerous work. Collectors climb between steep cliffs, and if they slip and fall into deep ravines, they will be shattered. It was collected for the first time, with pure texture and no hair attached. It is the top grade of bird's nest and is regarded as the "official swallow" of tribute; Secondary mining, because of the tight time, the nest is rough and contains more impurities, and it is only called "Maoyan"; Three times, it seems to be "quite pitiful".
