In the rainy season of late summer and early autumn, it was a misty rain similar to that in the south of the Yangtze River. In the mountains, the rain was filled with fog, and the rain dripped from the eaves. However, the towering green mountains seemed to be in the misty rain. As night fell, the rain brought a little coolness. Only then did people realize that it was already early autumn. After the rain, the dripping rain stopped and the leaves could be heard, qingquan flows in the mountains and forests. It is clearly a place with people, but because the trees in the mountains are luxuriant, they cover up the traces of people's activities. If it were not for the lights on, they did not know that there were people in the mountains. In the evening of late summer and early autumn, the scenery was beautiful. At that moment, they understood what the poet called empty mountains and new rain. Maybe I can use the feeling at that time to express what was originally abstract freehand brushwork, carry forward poetry, and make it continue to coruscate new vitality in a new form.
