The title of the poem is "Occasionally Written on a Spring Day", which refers to a short poem written impromptu on a spring day. Since it was "written by accident", the emotion in the poem should be a natural expression.
Looking at the nice weather outside and the bright spring scenery, Cheng Hao thought about going out for a walk, so he came up with the idea: "The clouds are clear and the wind is gentle at noon, and the flowers and willows are crossing the Qianchuan." Overall, Full of leisurely elegance. The weather was just perfect that day. I was walking in the countryside watching the light white clouds floating in the sky, blowing the warm spring breeze, and it was already noon before I knew it. Along the way, there were flowers and willows. Walking slowly amidst this beautiful scenery, we arrived at the riverside unknowingly.
Cheng Hao once said: "Everything has its own reason. If you go with it, it will be easy, and if you go against it, it will be difficult. Everyone follows their own principles, so why bother with your own efforts?" (Volume 10 of "Henan Cheng's Posthumous Letters" "Yi Mingdao") means that everything has its own "reason", that is, the law of its own development, and must not violate the law. The same is true for the great spring scenery in front of us. They are all developing according to their own "reasons". Naturalness and spontaneity can exactly show the most beautiful appearance and style of nature.
