Weibo saw a picture with six playing cards on it, asked you to choose a card with that card in your mind, stared at the picture, and then the card you chose below disappeared.

This is a kind of magic called "disappearing card", which is usually realized through some visual skills and psychological principles. The following is a possible explanation:

In this game, the magician will show six playing cards and then let the audience choose one of them. Then, the magician will make the audience pay attention, stare at the selected cards, put the cards behind their backs, and then change one of them. When the audience is paying attention, the magician can exchange the selected card with another card with a quick skill. In this way, when the magician takes the card to the front again, the selected card is no longer in its original position.

The effect of this magic depends on the audience's concentration and the magician's speed. Magicians usually use some language and body language to guide the audience's attention, so that they unconsciously ignore some details, thus making the magic look more magical.

It should be noted that this kind of magic is not a real magic or supernatural phenomenon, it just takes advantage of human visual and psychological weaknesses. If you want to learn this kind of magic, you can learn it by searching for some magic teaching videos or consulting professional magicians.
