Some people say that freshly peeled Wan Wenqing walnuts will be kept in the refrigerator for a while, right? Do you have any other opinions? How to play?
This is the first time I have heard of this method. All I know is that peel off the green husk, wrap it in a paper drawer, then put it in a paper box, and then put it in a wooden drawer or wardrobe 15 days before you can take it out to play. This is also what the old players said, hoping to help you.
