The first paragraph of my understanding of cows is like this: "My life is limited and my knowledge is limited. With restrictions, there is no restriction, and it is almost there! It's almost enough for people who already know! Good has no near name, and evil has no near punishment. The governor thinks that classics can protect you, you can live all your life, you can support your relatives, and you can spend all your years. "
Translated into modern Chinese, it means "my life is limited, but my knowledge is infinite." It is really dangerous to pursue infinite knowledge with limited life! There is danger, but also the persistent pursuit of knowledge, then there is nothing but danger. You don't need fame to do good, and you don't need punishment to do bad. With the aim of following the nihility of nature, you can protect your life, preserve your nature, save the opportunity of new life and enjoy your life. "
