Specific method
(1) Stand still and relax naturally. Take off your cotton coat in winter.
(2) Half-clenched fists. First hit the right chest with your left hand, then hit the left chest with your right hand, from top to bottom, and then hit the left and right chest 200 times from bottom to top. However, it should be noted that the flapping force above the chest can be slightly larger, and the downward force can be reduced. Do not use brute force to avoid damaging the body.
(3) clap your chest and back, with your hand still half clenched, and then clap your right back behind your head with your left hand.
Clap your left back, each time 100.
