1. Tap your soles. You can tie the child's hands and feet, then let him lean on the bed, put his feet out, pull his toes, then hit the soles of his feet with a ruler, tickle and so on. Until the child's soles are red and blue (preferably blue). You can also draw the soles of your feet with things like hemp rope, and it is best to draw them to blue and purple.
2, running, (preferably in summer) you can let the children run downstairs barefoot, or you can put things like pebbles, crayons and chalk, Lego bricks in socks first, and then let the children put on socks and shoes and run downstairs.
3, covering your sweaty feet, (if it is summer) wrap the tape around your child's feet and expose it to the sun. (If it is winter) Put tape on the child's feet and lean against the heater. Then let the child's feet be wrapped in tape for a month, and then run downstairs twice a day with two layers of socks and an airtight shoe, so that the child's feet will be covered with sweat. (If you have sweaty feet, it will be very uncomfortable, and the process of covering is also very uncomfortable. )
4. Scratch the soles of your feet, tie the child to a chair, then put a stool together, tie the child's feet to the stool, and then scratch the child's ankle with some tools, such as brushes, electric toothbrushes, blush brushes, feathers or directly by hand. Children will laugh hysterically, and children are very ticklish. This is how I was punished when I was a child.
