Life is like a ladder, rising step by step, this is a shared experience of human life; In the context of traditional Chinese culture, this "ladder of life" is not just a physical ascent, but also a spiritual awakening. From the phrase "Heaven is strong and virtuous, and a gentleman strives for self-improvement" in the Book of Changes to the prophet Wang Yangming's "cultivating conscience", from the flying ladder in Dunhuang murals to the moss marks on ancient temple stone steps, traditional culture always tells us in a metaphorical way that the advancement of life is always accompanied by the growth of the soul; The height of a staircase is ultimately measured by the thickness of one's spirit.
