According to historical data, as early as 1600 years ago, there was a wave of immigrants in Shenzhen, and mainlanders made great contributions to the development of Xin 'an. The county is located in the east of Guanxian County, with Baoan as the first, and the county and the county are in the same jurisdiction. It is a traffic hub of rivers and seas and an important coastal defense town. Therefore, Xin 'an City has become the source of Shenzhen's urban development and the political, economic and cultural life center of Shenzhen. Historical changes are often manifested in Xin 'an, so are the development and changes of cities. In the sixth year of Liang Dynasty (507), the county governing the east will be changed to Dongguan County, and Chen Junzhi will be moved to De 'an for two years (757), Baoan will be changed to Dongguan, and the county will be transferred from the southern end to Dongguan today. After the Five Dynasties, the administrative subordination of Song, Yuan and Shenzhen all changed. Today, we saw the southern city, namely the twenty-seventh year of Hongwu, Guangming City (1394), and Ho Choi, Zuojiankang, Guangzhou, built the "Dongguan Qianhu City" at the original site. In the first year of Wanli in the Ming Dynasty (1573), Xin 'an County, a branch of Dongguan County, was established, with this city as the county seat. According to archaeological discoveries in recent years, Shenzhen has a history of 6000 years. According to the information about underground archaeological excavations and ancient sites on the ground, Shenzhen has a long history. The pottery and stone tools found in the mound sites of Dahuangsha and Dameisha show that as early as the Neolithic Age 56,000 years ago, human beings lived in this beautiful and rich land. Created the glorious history and culture of Shenzhen. At present, it has been found that there are cultural sites 103, 234 ancient tombs, 68 ancient buildings and historical memorial buildings, 97 modern historical symbols and revolutionary memorial buildings, and 12 old customs stations and boundary pillars in Shenzhen. After screening, the municipal government announced 36 cultural relics protection units in three batches. Dapeng Bird City and "Chinese Culture Street" boundary pillar 1989 were recognized as provincial cultural relics protection units by the provincial government.

Shenzhen is located on the coast of South China Sea in China, with coconut trees, fine waves and white sand, and pleasant scenery. It has always been regarded as "the south gate of China, the scenic spot of the company". Since the Eastern Jin Dynasty, Shenzhen has always played an important role in politics, culture, economy, transportation and coastal defense. Archaeological data prove that as early as 56,000 years ago in the Neolithic Age, human beings worked, lived and multiplied in this beautiful and rich land of Shenzhen.

Since the Qin Dynasty, more than 100 ethnic residents in Shenzhen have been under the feudal centralized rule. China people once set up officials in Shenzhen, and found Han tombs in Xixiang, Shajing, Dapeng Bird and Hongzhengwu Village in the four townships at the southern end. Judging from the literature and archaeological discoveries, the Central Plains culture was integrated at that time.

During the Eastern Jin Dynasty and the Southern Dynasties for more than 250 years, it was the prosperous eastern part of Shenzhen, with six counties, including Guanxian, Lingbao, Ning and Ningxing, covering the Pearl River Delta and Huiyang. At that time, Baoan was probably under the jurisdiction of today's Dongguan, Shenzhen and Hong Kong.

In the Tang Dynasty, Shenzhen waters became an important place for sea route transportation. Located in the storage town at the end of the south of the city, there are Lingnan soldiers; Since the Song Dynasty, Shenzhen has become the hub of South China's maritime transportation and trade, and has made great economic development.

In the twenty-seventh year of Hongwu in the Ming Dynasty (1394), Dongguan Shouqianhu City and Dapeng Bird Shouqianhu City were built at the southern end of Shenzhen's historical revival period. Later, a stronghold was set up at the southern end, forming a large military institution, which was "Humen's external protection and the provincial capital's resistance to dwarf crowns, pirates and all foreign invaders". Ming 16 (152 1 year), soldiers and civilians at the southern end patrolled under the leadership of Wang Hong, and wiped out the Portuguese fleet in the southern waters.

The number of residents in Xin 'an County who have settled in Lin 'an has reached 225,979. The population has greatly increased, and agricultural production, fishery and salt industry have been greatly developed.

In the second year of the southern tip of the Republic of China (19 13), Xin' an county resumed security, and its administrative office was still located in the city. At the stage when the old democratic revolution began with the new democratic revolution, the people of Shenzhen wrote an inspiring chapter for national liberation. In particular, the anti-Japanese guerrilla troops stationed in Dongjiang were active in Huidong and Baodi areas, maliciously attacking Japanese invaders and escorting cultural figures stranded in Hong Kong to the liberated areas, which made great contributions to the cultural construction in China.

Shenzhen has a long history and developed culture, so it is rich in cultural relics and numerous scenic spots, such as "Jin Nian Sui Yuan" Temple in Jin and Sui Dynasties, Haiguang Temple and Lingdu Temple in Tang Dynasty, Tianhou Palace in Chibi in Southern Song Dynasty, "Eight Scenes of Xin 'an" in Ming and Qing Dynasties, and Gushan, Longqiao and Qiniang Mountain.

In the1980s, after Shenzhen was designated as the first special economic zone in China, the tourism industry developed extremely rapidly, and the newly-built scenic spots and facilities were unique and famous at home and abroad for their novelty, uniqueness and different styles.
