Life is best if it is full, which means it will be full, and there is still room for improvement, so it will not be full and lose money. Life is best. As the saying goes: when the moon is full, it will lose money, when the water is full, it will overflow, and everything will inevitably go downhill after reaching the extreme. Great fullness is not the perfect state pursued by the ancients, but "small enough to be full" means that there is room for the immature to grow up, and it can also be "increased", which happens to be the best state of life.

In ancient China, Xiaoman was divided into three stages: "Waiting for the bitter vegetable show, waiting for the grass to die, and waiting for the wheat to arrive in autumn." That is to say, after the full solar terms, bitter vegetables have flourished; After that, some grass with soft branches that like shade began to die in the strong sunlight; In the last period of Xiaoman, the wheat began to mature. At this time, the seeds of summer crops such as wheat in the northern part of the country have begun to be full, but they are not yet mature, which is about the late stage of milk ripening, so it is called Xiaoman.
