In this world, the most interesting thing is the clear and faint joy. This poem comes from Huanxisha written by Su Shi, a famous poet, calligrapher and gourmet in the Northern Song Dynasty. The whole poem has a beautiful artistic conception and is full of the breath of spring. This is a work that records what you saw, heard and felt during your trip. Among them, the word "Qing Huan" is understood by most people as "light and happy", which highlights a sense of indifference, has a unique charm and contains ordinary and valuable life insights.
