Time is invisible, the rising and setting of the sun, year after year are called years; the years cannot be retained, the flowing water and the breeze pass away like this, without a trace.

In the diary, whether it is the outpouring of troubles or the dazzling splendor or the indifferent ordinary, they are all confessions of your true feelings and elements of your life trajectory.
