1959, in order to build Xin 'anjiang Hydropower Station, the largest water control project at that time, the former Chun 'an County and Sui 'an County of Zhejiang Province merged into the present Chun 'an County, and 290,000 people moved. Two ancient cities, Shicheng and he cheng, which lasted for thousands of years, together with 27 towns, 1000 villages, 300,000 mu of fertile land and thousands of houses, quietly sank. The ancient city of Chun 'an, also known as he cheng, was founded in 208 AD. Huizhou House under the elaborate "Shang"-shaped portico in the shape of an ancient coin shows the prosperity and wealth of this Huizhou merchant hub on Xin 'an River. Throughout the ages, there are many literati here, famous artists and cultural relics everywhere. The history of Sui 'an is later than that of Chun 'an. According to records, Sui 'an County moved to Sui 'an boundary in the fourth year of Wude in Tang Dynasty (AD 62 1 year), and it was also called the Lion City because it was backed by Wushi Mountain. Lion City, with convenient land and water transportation, is an important town in western Zhejiang. Hong Rengan, Hong Xiuquan's brother, once led the Taiping Army stationed in the north gate. There are many places of interest in the Lion City, including ancient pagodas, memorial archways, Yuemiao, Chenghuang Temple, Zhonglie Bridge, Wushi Academy and ancient tombs. In the eyes of many cultural relics protection experts, the "flooded Chun 'an City" was quite hasty. It stands to reason that before the reservoir is built, it is necessary to "clear the reservoir", raze the building, remove the garbage and relocate and protect the cultural relics. According to historical records, before the storage of Xin 'anjiang Reservoir, people's houses in two local counties were required to be leveled, destroyed and disinfected, and he cheng was basically destroyed. At that time, there was such a slogan: "Bring more new ideas and less old furniture."

The old man who moved out of the ancient city recalled, "The Lion City is far from the dam. People in the city didn't expect the water to come so soon, and it was too late to move. " Therefore, it is generally believed that the ancient lion city is basically intact.

There are five gates in the Lion City, namely East Gate (Xingwen Gate), South Gate (Xiangming Gate), Xiaoximen (Kangfumen), Daximen (Wujingmen) and North Gate (Gong Ji Gate), and towers are built on each gate. The roof of the city is covered with huge stone slabs, surrounded by bricks, with arches on both sides, riding on the wall. The northwest corner and the northern half of the city wall are built on the mountain, and the terrain is high and steep, which is particularly spectacular. The main streets in the city are East Street, South Street, West Street, North Street, Straight Street and Hengjie. The intersection of East Street, North Street and Straight Street is the most lively square in front of the county government. The lion city mainly includes Wang, Yao, Yu, Fang, Hu, Wang and Huang. As a corner of ancient Huizhou, Lion City is also deeply influenced by Huizhou merchants and Huizhou culture, with many skilled craftsmen and many cultural relics. There are West Temple at the north gate, City God Temple at the south gate, Sansheng Temple at the west end of Zhijie, Kang Wang Temple at the fierce bridge head of Xiaoximen, Confucius Temple and Dongyue Temple in front of Confucianism at Daximen, all of which are relatively large in scale. There are also many places where there are filial piety, fame, merit square and ancestral halls of various surnames. There is an ancient clock in the back hill of Beimencheng, which weighs three thousand kilograms. In the 16th year of Yuan Dynasty (1270), it was collected by Huang Tu Zhiyuan, Shen Gong Road, Sui 'andong, and the attack sound was 10. During the War of Resistance against Japanese Aggression period, Japanese warplanes often bombed the city, and this clock was used as an air raid alarm. In the forty-first year of Wanli in the Ming Dynasty (16 13), Liu Yunyuan, a metallurgical worker, also cast a big tripod and stood in front of Kang Wang Temple. There is a Catholic church and an East Temple outside the East Gate. There is a seven-story pagoda on the hill next to Shijia Village, two miles from the city. It's called Queventa. Yangcun Bridge outside the south gate is a stone bridge in Ming Dynasty, located at the junction of Yuxi and Wuqiangxi. It is a nine-hole bridge, also known as Jiumen Bridge, with a single span of more than 8 meters. It was funded by Wang Qiaonian, assistant minister of the Ministry of War of the Ming Dynasty. The "Gong Jin Dike" along the Wuqiangxi River was proposed by Jin Naiguang, a magistrate of a county, in the 10th year of the Republic of China (192 1).

Historically, the Lion City used to have cultural facilities such as academies, nursing homes and nurseries. After the end of the Qing Dynasty, primary schools, Taiding primary schools, teacher training workshops, health centers, county popular education halls (later changed to people's education halls), Shishan Park and Gong * * * Stadium (within Confucianism) were successively established, and then simple normal schools and junior high schools were added. In the early days of liberation, film projection teams and mass cultural centers were added.
