You can consider the bird's nest I'm making now. Personally, I think it is easier to do. The brand is big, the market is good, the product price is not expensive, the threshold is not high, and there is no need to stock up. You can consider that Han Chengxing's bird's nest sells well, especially the new freeze-dried bird's nest, which is the cup-shaped bird's nest. It is cheap and affordable and sells well! I hope Baidu will adopt it
