How to Distinguish Ya Song and Ya Bai


Ya Song

  1. Taste

  This is the most effective method of distinguishing them. If you can't tell from their appearance, you can distinguish them by their taste.

  Ya Bai has the taste of cypress, while no matter how aged Ya Song is, it will always have the taste of pine, which cannot be changed!

  2. Texture

  Ya Bai has gorgeous textures such as Bodhisattva cloud patterns, tiger skin patterns, and ink patterns.

  Ya Song does not have as many gorgeous textures! Can Ya Song have Bodhisattva cloud patterns? That doesn't exist!

  3. Fineness

  When looking at the raw materials, the texture of Ya Bai is very fine, while Ya Song is not as fine as Ya Bai.

  The "coarse silk" of Ya Song is rough! The texture is not as fine as Ya Bai!
