According to Qianlong's Records of Huai 'an County Volume 5 City and Pass, Liu Huaiguan is Shimonoseki. Xiaguan Town, the ancient Xiaguan, is a famous city in the east of the city, namely "Yecheng". Shimonoseki originally had a slate street and a blue brick wooden house, and the architectural style was similar to that under the river. Unfortunately, Shiban Street was replaced by cement pavement in a reconstruction of Xiaguan Street twenty years ago. Merchants along the street have not only achieved economic development, but also transformed their storefronts and living environment. Wooden houses are rare, but the old pattern of Guzhen Street in Xiaguan Street is still well preserved, and many historical sites still remain inside. The old names of streets and lanes are still used, such as Tangzi Lane, Hehe Lane, Anle Lane, Jiabu Lane, Guandimiao Lane, Shazhu Lane and Zainiu Lane. Historically, there used to be temples and ancestral temples here: Shuiyue Temple, Zhaoxian Temple, Guandi Temple, Land Temple, Ruyi Temple, Jixiang Temple, Dizang Temple, Yuntai Temple, Tokyo Temple, Baiyi Temple, Mars Temple, Sea Temple, Land Temple and Dangshen Temple. Among them, the name of the Sea Temple frequently appears on the regional map of Huai 'an Prefecture, and sometimes it is not displayed in the map. According to records: "Shimonoseki Sea Temple has a temple fair every year, which will be held on the tenth day of the fourth lunar month. The ninth day is a small meeting. Groups of kind men and women gathered here to burn incense and pray for God's blessing. 10, played 5 drums. The day before yesterday, the main hall built a tripod with long bamboo and hung a string of firecrackers. Bare-chested, with an iron needle on his wrist and Strafe in his hand, Ma Yi jumped back and forth in the fireworks of firecrackers to welcome Neptune to the altar. The servants carried the idol out of the palace, led by flags, gongs, umbrellas and fans, guarded by melons and axes, wrapped in cigarettes in Qinghai furnace, accompanied by flower bears, jade bears, flower drum parties, flower basket parties and incense parties. God is sailing in the south tower and patrolling the south by boat. The ships are connected end to end, the gongs and drums are loud, the national flag is flying, and it is beautiful and dazzling. In the afternoon, Zhibao went to the altar of Taishan Temple. The congregation went to Mount Tai Temple to burn incense on foot, by boat or by unicycle. The next day, Shen Jia still put the boat back on board. During the guild, the incense in the Temple of Sea was in full swing, and the temple was anxious to prepare jiaozi for pilgrims to eat. As the saying goes, "jiaozi in the Temple of the Sea is ready-made" [quoted in this paragraph]
Shimonoseki also has some necessary non-governmental organizations, such as the Guanshui Dragon Bureau, a "Zhongshikou"; On the east side of Rendong Bridge, there is an old bathroom "Rixin Pool" with a history of more than 200 years. Unfortunately, it is beyond recognition, and most of it no longer exists.
Historically, Shimonoseki also played an important role in the whole defense system of Huaicheng. Because Shimonoseki and He Xia are symmetrical on both sides of the north of the city, dikes with watchtowers and camps have been built in all previous dynasties. From the Song and Jin Dynasties to the Qing Dynasty, when the nomads from Huai 'an were prevented from attacking the city, the Huai 'an government supervised the construction of outer stockades around Daxing princes. "The battle of surrounding stockades flourished" and "from the northeast corner of new city to the east of the city" was called "Xiaguan besieged city".
