Zijin Mountain is known as the mother mountain of Nanjing people. Although the highest peak is only 448 meters above sea level, its area is vast. It is surrounded by about 30 miles. Zhongshan Mausoleum, Ming Xiaoling Mausoleum, Linggu Temple and Meiling Palace are all in the scenic spot of Zijin Mountain. They were praised as "Yuxiu in Jinling", "Longpan in Zhongshan, Tiger in Shicheng". I climb Zijin Mountain and often receive extra goods. Once, climbing from White Horse Park and traveling through the quiet jungle, we found a low lake, called "Lake Biwa". The lake is very small, but very quiet. The walls of the Ming Dynasty are towering. It is closely related to the lake. There are small pavilions and long wooden trestles along the lakeside. The grass along the lakeside dances in the breeze. The whole lake and the surrounding terrain are in a lower region, which seems to be a basin. Only standing on the edge can we see that there are really holes in the sky. Ever since my son and I found this lake, we visited it every three or five times. We often saw people in twos and threes, sitting in pavilions or nestling by the lake on the grass. Several times, I saw several singers, in the pavilion on the left, blowing saxophones, accompanied by accordion, humming their songs softly. Music, song and bird's call are interwoven into a beautiful and colorful world. It seems that the clouds are blooming, beautiful and long. On the right, some old people are discussing current affairs. From the war of liberation to the international situation, from the educated youth to the countryside, to the civil strife in Xinjiang. There is a university professor, retired leisure, talking to you from the Eastern Zhou Dynasty to the Ming and Qing Dynasties, to understand the past and the present. We moved from the music booth to the political booth. Sometimes new people came and sat down to listen. Some of them were tired of listening. They stood up and said hello "You talk, I stroll" to the people they didn't know. A young man went to the pavilion of saxophone and accordion and looked at the music score with them. Sometimes he asked in a low voice, sometimes he smiled softly. On another occasion, I met a camera crew, with cameras, organized, and many people dressed in antique clothes. They were very beautiful. They must be shooting a play. Some have long swords, some have short knives. Most people wear wigs of different colors, with a long white eyebrow, which reminds me of the "White Eyebrow Man" I saw as a child. Naturally, in this beautiful and leisurely place, people who are about to get married often come to take wedding dresses. Thin white wedding dress, gently swinging in the wind, is very beautiful. In autumn and winter, there are many waterfowls, small birds swimming back and forth in the water and the shore. When it is cold, they are not afraid of the ice and walk proudly on the ice. It reminds me of the emperor in his invisible new clothes. They are not afraid of people at all. My son often picks up "souvenirs" under trees, fruit like a bird's nest, or odd-shaped leaves. Often let me save it for him, saying that when I grow up, I want to look at them as memories. But there are so many, I throw away a lot. He is too obsessed with this beautiful place to find my little action.
