Cuiyun Corridor.

Qiao Bo, the governor of Jianzhou in the Qing Dynasty, wrote the poem "Cuiyun Corridor, protected by green smoke, moss and flowers in the shade, rain wets clothes, branches and leaves hang down, cool breeze blows by". Since then, the name "Cuiyun Corridor" has been preserved. According to archaeological data, most of the ancient cypresses that wind for more than 300 miles in Cuiyunkuo are natural forests, and a few are artificially planted. The "Cuiyun Corridor" named in the Ming and Qing Dynasties is more than 300 miles long, from Jiannan to Langzhou and west to Zitong, with tens of thousands of ancient cypresses. In fact, the ancient cypresses stretch for more than 300 miles as described in the Ming and Qing Dynasties, but for at least 700 to 800 miles, from Qiqu Mountain in Zitong County to the south and Jiange to Mian County in the north, all of which are green mountains and lush natural cypress forests. The Shu Road was the main road leading to Chang'an in ancient Shu, and was also an important transportation hub for foreign exchanges in ancient Shu. The Shu Road is divided into the Four Qinling Roads, the Jinniu Road and other small roads leading to Shu. The Shu Roads are "four in the north and three in the south". The northern ones are Chencang Road, Baoxia Road, Tangluo Road, and Ziwu Road; the southern ones are Jinniu Road, Micang Road, and Litchi Road. The main road in the north is Baoxiade Road, and the main road in the south is Jinniu Road. Jinniu Road is the earliest road in Shu. Cuiyunlang Ancient Shu Road is located on the Jinniu Ancient Shu Road. Due to the unique soil conditions in Jiange, this place has become a paradise for the growth of cypress trees. Cuiyun Corridor is arranged in the shape of a "human" character, extending to the ancient city of Zhaohua in the north, the ancient city of Langzhong in the south, and Damiao Mountain in Zitong, Mianyang in the west. There are 7,803 ancient trees in Cuiyun Corridor of Jianmen Shu Road, including 7,778 ancient cypresses with an average age of 1,050 years. According to research by forestry experts, the ancient cypresses along the Cuiyun Corridor with a trunk diameter of more than 2 meters and a tree age of more than 2,000 years were probably planted during the Qin Dynasty. Cuiyunlang Scenic Area is one of the core scenic spots of Jianmen Shu Road, the first batch of national key scenic spots and national key cultural relics protection units, and is also a national forest park. The ancient cypress trees in the area are lush and full of vitality. They began in the Qin and Han Dynasties and were completed in the Ming Dynasty. They are a rare group of artificially planted ancient street trees. Cuiyun Gallery
