I have a classic tarot card, but I still don't know how to shuffle it. There is no specific guidance. I heard from my friends that it depends on my age. It's confusing. How to start?

There are two ways to shuffle cards. One way is to mix cards clockwise or counterclockwise, just like mahjong, until you think you can. Another way is to draw a stack of cards from below and stack them on top, just like playing poker, because tarot cards are divided into positive and negative positions, and you can discard them after washing them for a while. As for the way of shuffling cards, it hurts the cards too much. Let's leave it to poker.
