The idea of harvest comes from the perception of the harvest scene in Van Gogh's works. Life is actually like nature, sowing, cultivating, and harvesting. When young, harvest youth and vitality; In adulthood, harvest maturity and charm; In old age, gain experience and wisdom; Harvesting peace and tranquility in old age; When successful, harvest joy and happiness; When you fail, gain experience and lessons. In the course of life, everything must have a harvest.
