I picked walnuts on the mountain all day, and my hands are black. How can I send a message?

Walnuts picked in the mountains all day are black. You can say: the crispness of a walnut lingers in your mouth, a month's fatigue evaporates in your smile, and a person's thoughts are conveyed in a short message. Because it can cause a lot of people to curse, so it can be said. Walnut is a common edible nut and the fruit of walnut. It is the fruit of Juglandaceae, with a hard shell and edible nuts (also called walnuts) inside.
