The purpose of fixation is to protect the yang, but if it does not dissipate, the kidney yang will not be pulled too much, thus strengthening the yang in the kidney. What is dissipation? Staying up late, drinking, being grumpy, having too much sex, etc., are all called dispersion, which means that we can hold and protect the yang in our bodies and prevent it from dispersing too much. Yang is stored in the kidney and then rises from the liver, so actually holding is to protect the liver and strengthen the kidney. Putting your thumb at the root of your ring finger actually works.

When we are babies, because the baby itself is still weak, we need to protect the yang, so the baby instinctively protects itself by hugging tightly. When we grow up, it's really a huge waste to forget this instinctive trick! Anyone who is interested, learn to do it and keep doing it, and you will know how powerful it is!
