Let me give you an example. Ten cards are converted into codes in turn: 25, 40, 37, 36, Yang Guifei, 29, Lu Bu, 44, Liu Bei, 10. The first place is the entrance of the community: the first card is red heart 5, the code is 25, and the corresponding item is erhu; The second card is 10, code 40, and the corresponding item is the commander. Imagine a story. A huge erhu fell from the sky at the gate of the community, killing the conductor. The location is the security booth: the third card is Meihua 7 pheasant, and the fourth card is Meihua 6 mountain deer. Imagine this story. In the security booth, a pheasant escaped from a deer. The location is the hive express cabinet. The fifth card is Q Yang Guifei of diamonds, and the sixth card is 9 Hungry Prisoners of Hearts. Imagine this story: Yang Guifei turned to work as a courier to deliver food to hungry prisoners in her cell. The location is the community kindergarten: the seventh card is Diamond J Lu Bu, and the eighth card is Diamond 4 Snake. Imagine this story: in kindergarten, the fierce Lu Bu held a snake to scare children. The fifth place is the community gymnasium: the ninth card, Liu Bei of spades J, the 10 card, and the spade 10 baseball. Imagine this story: in the gym, Liu Bei with big ears is playing baseball. So you can remember ten cards, then close your eyes and review what happened everywhere. When someone asks you for the eighth card, push it back. The eighth card is placed in the fourth kindergarten. The story that happened there was that the evil Lu Bu held a snake to scare children, so the eighth card was a snake, the snake was 44, and then the box was 4. So you can find 26 places and write down a deck of cards. Let's start practicing. It may take more than twenty minutes for the first time, and it may be done in ten minutes if you are skilled. It won't be a big problem to practice a deck of cards for two minutes several times. If you want to be more awesome, just keep practicing. Practice makes perfect. It's possible in a minute. In fact, the method used by the world poker memory champion is actually the same principle, and the other is to practice more. You may ask, what's the use of remembering playing cards? In short, this is a good way to exercise memory, and its method can be extended to remember other things, that is, to use your imagination to remember. Including English words. Okay, so much for the memory card, so much for the memory card.
