Turtle rest, Taoist language and turtle rest therapy refer to a way of practicing bionic breathing with the help of turtle's hibernating breathing method. It is said that breathing is like a tortoise. You can live forever without drinking or eating.

When I said it, I thought that when the tortoise slept, its breath came out of its ears, so it lived forever. According to legend, the turtle's breathing skill consists of four parts: concentration, latent breath, truth and determination.
