Ancient literati Zhang Dai wrote in Viewing the Snow Scene from the Mid-Lake Pavilion: "Over the lake, the curling mist and fogs mixed with the fluttering flakes made the sky, the clouds, the hills and the waters all white, high and low. The only shadows I could see in the lake were that of the long causeway which was reflected in the shape of a belt, that of the Mid-Lake Pavilion in the shape of a dot, my boat – a leaf and the men in the boat – a couple of rice grains. " When the snow falls, the earth and the sky are connected at this moment, the trees record the language of nature, and people are in it and one with nature.
