Explain the stall in simple words is airplane lose lift and drop by gravity. In the training, the short time that the airplane drops is so exciting.

失速，用相对通俗的语言可以解释为：飞机失去了升力，然后在重力的作用下做面向地面的垂直运动。在训练中，飞机垂直下落的短短的时间很让我回味哦。

Relax your arm (the whole body, actually), keep your wrist flexible, lift the hand from 5 to 20 cm above the keys (the shorter distance in the beginning), and let gravity drop your hand.

手臂放松(事实上是整个身体都要放松)，保持手腕柔软，然后将手抬高离开键盘5至20公分(开始时用较短的距离)，让手自然放下。
