What does it mean to adjust the front fork turtle and rabbit?

Most pneumatic front forks have the function of adjusting rebound damping. The regulating valve is located under the damping fork barrel, and the main function of damping is to limit the rebound speed of the front fork. When the rebound speed is too fast, the front fork may not fully absorb the impact force and even interfere with the driver's operation. Most pneumatic front forks have the function of adjusting rebound damping, commonly known as "turtle-rabbit adjustment", so the turtle-rabbit adjustment of the front fork is the function of adjusting rebound damping of most pneumatic front forks. When the tortoise and rabbit are adjusted, the front fork will rebound slowly when it is closed. It bounces back as soon as it is opened.
