What do you mean by "class money"?

(1). Tax amount. Shen Ming Telford's "Four Dialectists by the Leaf Fire": "The class in Huaibei is the best in the world, and the one with the highest appearance is the best."

(2) the reward of divination. Journey to the West said in the tenth time: "If it rains tomorrow, I will give you a class fee of 52 taels according to the time and times of rest." Qing Li Yu's "Fake Disease": "The words have been finished and the lessons have been given."

(3). Class money (かきん). Words in Japanese games. Refers to the payment of materials, especially the recharge behavior in free games. Later, because there is an expensive metal called krypton in the famous online game "World of Warcraft", domestic players usually use krypton to indicate that online games pit money. Over time, lesson gold and krypton gold were confused by most people.
