This is Laozi's life and thought: "Misfortune is on it, and happiness is on it", "Misfortune is on it, and happiness is on it." It means that misfortune is the premise of happiness, and happiness contains unfortunate factors. In other words, good and bad things can be transformed into each other. Under certain conditions, happiness can become a curse, and a curse can also become a blessing. This famous saying of Laozi is very reasonable.

There are only 5,000 works left by Laozi, namely Tao Te Ching, also called Laozi.
