No need to wash, these are all processed, just eat them directly, just like walnut kernels, you need to buy sweet almonds.
I am eating organic sweet almonds from Shansheng Youxing. They are very good. You can try them. I bought them in Zhengzhou. If you are not from Zhengzhou, you can go to their store on Taobao. The ones sold on Taobao are the same as those sold in the store.
