Outside the building are green mountains and green waters, but inside the building is the ups and downs of life year after year. When a young man is born, the world is full of tall buildings and crowded with people. There is also scenery outside the Qingtian Tower, but it is difficult for a passerby in this mortal world to appreciate it.
Purpose: Strive to be a young man in this world, be high-spirited and not envious of immortals.
