What's the difference between identifying swallow cups, stripes, horns and broken swallows?

There are many things in life that are highly similar and difficult to distinguish. Let's talk about how to distinguish between swallowing lamps, strips, horns and pieces.

0 1 swallow cup retains the complete bird's nest shape when picking, and can be divided into flat cup (half moon shape) and triangular cup according to the shape.

Yan tiao is a broken lamp in the process of picking, processing or transporting bird's nest. Swallow cups and stripes can be distinguished from each other in shape.

The corners of the bird's nest are the parts that support the weight of the whole bird's nest, and the parts where the two ends of the bird's nest are connected with the wall are matched with the complete cup-shaped bird's nest, which is cut by workers when picking hair.

Broken bird's nest is the broken part of bird's nest during picking, cleaning or transportation, but it can't be turned into swallows.
