I know the most expensive one is 990 thousand. Personally, I feel that walnuts have been carried to such a high price, which is really impossible to evaluate. Walnut in Wan Wen is a hobby in itself, and it is Er in A Le. Spending 990 thousand on a walnut only shows that the buyer has money and nowhere to spend it. The most important thing for walnuts in Wan Wen is to experience the fun in the process of making walnuts. How much is worth is not the most important thing.
