1. Your birth is important. The bird's nest is made of saliva by Jin Siyan. The original bird's nest is a natural wild cave swallow, which is mostly built on the cliffs or caves of tropical and subtropical islands. The terrain is steep, the collection is quite dangerous and the number is rare.

2, your processing technology. Pure natural and good bird's nest without additives must adopt a pure manual hair picking process, which is not only time-consuming but also cost-consuming. It takes about 4 minutes for a skilled bird's nest picker to pick out a bird's nest that meets the cleanliness standard. This is a low-efficiency and high-cost processing process. Of course, the high processing cost also raises the price of bird's nest.

3. The most important thing is the nutritional value. Bird's nest contains water-soluble protein, which is helpful for the growth and development of human tissues and the recovery after illness; Bird's nest contains 22 kinds of active amino acids, which is the cornerstone of protein. Bird's nest also contains various trace elements, epidermal growth factor, bird's nest acid and so on. It plays an important role in nourishing, recovering and resisting germs.
