Yanziji is located outside Guanyin Gate, Qixia District, Nanjing City, Jiangsu Province. As the first of the three famous rocks in the Yangtze River, Yanziji is known as "the first rock in the Yangtze River". Yanziji is 36 meters above sea level, and the stone peak is abrupt on the river, facing the sky on three sides, and it is named after the swallow spreading its wings. "Yanji Sunset Red" is one of the 48 scenic spots in Jinling. There are Hongji Temple, Guanyin Pavilion and other buildings near Yanziji. There are 12 caves in Yanshan Mountains, which were formed by the impact of river water. Most of them are cliffs, among which three caves are the deepest, widest and deepest. Yanziji has always been close to the great river, and the terrain is dangerous. It is an important Yangtze River ferry and military fortress.

Caishiji

Caishiji is located on the east bank of the Yangtze River, 5 kilometers southwest of Maanshan City, Anhui Province. It is said that "The Story of Quarrying" was named after the colored stones produced here during the Wu Dong period of the Three Kingdoms, and it was also called "The Story of the Bull Beads" because of its snail shape and the legend that "the Taurus came out of Zhu Zhu". Caishiji has always been a scene in the south of the Yangtze River. Throughout the ages, many literati have used this as a topic to write poems, especially Li Bai, a great poet in the Tang Dynasty, who used to drink and write poems here. It is said that he finally drowned because he was drunk and wanted to catch the moon in the river, which added to his mystery.

Chenglingji is located on the right bank of the intersection of the Yangtze River and Dongting Lake at the northeast of Yueyang City, Hunan Province 15km, 7.5km away from the urban area and across the river from Jianli County, Hubei Province. "Notes on Water Classics" records: "There is Chengling Mountain on the right bank of the river, and the mountain has an old city." According to various historical documents, there should have been a rock head in the past, near the river bank, between Dongfeng and Bajiao Lake in the north and south, facing Jingjiang River, which became an island rock head surrounded by water on three sides, which was the node of Dongting Lake mouth on the south side of the cliff-shaped waterway here. But because this rock head is soil, it can't stand the long-term river erosion, and now it is gone. Now Chenglingji is just a place name. Chenglingji Port here is an important container distribution center in Hunan, with unique deep-water berths and first-class mechanized operations in Hunan.

If you visit Yanziji and Caishiji, if you want to get together and compare the similarities and differences of the three famous cities, you will be disappointed.
