1. The appearance and shape are different. Bird's nest silk refers to the thin, silk-like strips inside the bird's nest, which are usually relatively small. Its nutritional content is similar to that of bird's nest or bird's nest strips. Bird's nest silk is referred to as bird's nest, which refers to a complete bird's nest. The bird's nest is made of a strip of bird's nest. It is composed of strips of swallow strips, which are a complete line of spit coagulation produced by the swiftlet's saliva.

2. Difference in price. The price of the complete bird's nest cup is more expensive than the price of the bird's nest silk, because the bird's nest is easily broken during the process of removing fine hair and dealing with impurities, so the more complete the bird's nest cup, the fewer impurities and the heavier the weight of the bird's nest cup, the higher the price. It will also be more expensive.

3. The appearance is different. Under normal circumstances, bird's nest lamps will retain their complete appearance, such as half-moons and triangles, and are suitable for being placed in gift boxes for giving away; while bird's nest silk will generally appear in fragmented and irregular strips. More suitable for self-consumption.
