The bird's nest includes Bai Yan, Dongyan and Xueyan. If you want to buy Dongyan or Baiyan (estimate your economic situation and choose Baiyan).

Maybe you can see broken swallows, striped swallows and phoenix tails. You'd better choose a tuxedo. After all, you don't know what it is made of.

In the choice of bird's nest, you still need to know the difference between true and false bird's nest. Do not buy fake bird's nest.

I hope I can help you!
