The so-called gathering and dispersion of life actually refers to: far and near, high and low, deep and shallow, right and wrong, new and old, complex and simple, noisy and quiet, clear and turbid, rich and poor. All of the above are always entangled between one person and other personnel in the first half of life, and it was not until the second half that I discovered that all the past events in life were only between myself. This should be exactly what Mr. Mu Xin said: People should go back from a distance, go down from a height and go out from the depths.
