Last time, we talked about using Baoding balls to help exercise your hands and mind. Today, we delve into the pressure points on the hand and how they can help fix what ails you in the rest of the body. Unfortunately, we ran out of time after we reached the middle finger. 

上次，我们讨论了如何使用保定铁球来帮助锻炼手部和大脑。今天，我们将深入探讨手上的穴位，以及它们如何帮助缓解身体其他部位的不适。遗憾的是，当我们讲到中指时，时间就用完了。
