There are many examples of place name culture in zhenhai district, Ningbo: 1. The origin of Houhaitang II. The origin of Zhaobaoshan.

Zhaobaoshan Scenic Area is located in the northeast of Ningbo, where the surging Yongjiang River flows into the sea. It is the gateway of Zhenhai, the throat of Yongjiang River and the fortress of coastal defense. Known as the "gateway to eastern Zhejiang", it is a comprehensive scenic spot integrating sea and sky scenery, human landscape, coastal defense sites, religious culture, champion culture and academician culture. Zhaobaoshan Scenic Spot is a national AAAA-level scenic spot. In 2007, it was rated as "50 Excellent Scenic Spots in Zhejiang Province" by Zhejiang Tourism Bureau, and it is one of the top ten scenic spots in Ningbo.

As a scenic spot in Zhenhai, Zhaobaoshan has a long history. It not only attracts tourists with its Baotuo Temple and Lu Kun Guanyin, but also has a hundred years of incense and beautiful scenery, especially when it reaches its peak. The vast sea is full of water and sky, and the islands in the East China Sea are looming. Looking down, there are many tall buildings, power plants and refineries, rivers and seas, railways and highways criss-crossing, which is spectacular. But more importantly, Zhaobaoshan is located in the southeast coast of the motherland, leaving many brilliant historical sites and rich and precious coastal defense sites to resist foreign aggression since the Ming and Qing Dynasties. This is a historical testimony that Zhenhai people love the motherland, are not afraid of violence, and resist foreign aggression. It is a rare excellent cultural heritage and precious spiritual wealth of the Chinese nation.

Houhaitang was originally a city protection barrier against geomantic omen. It was built in the fourth year of Tangganning (AD 897) and has a history of over 1090 years. At that time, the earth pond had been built. Because of the "fear of breach", it was changed into a stone pond in the sixteenth year of Song Dynasty (1 189), but it still failed to withstand the impact of hurricane waves and collapsed many times. In the 13th year of Qing Qianlong (1748), Wang Mengbi, the county magistrate, submitted a form to resist the invasion of the tide, requesting the court to allocate funds to repair the pond. After extensive investigation, the king county magistrate adopted many opinions and thought that "a thin stone can be solidified forever", so he rebuilt 576.5 feet of the top mezzanine stone pond, repaired 396 feet of the second section stone pond, built 5 1 foot of the new stone pond and repaired 8 10 feet of the collapsed city in the north. He personally directed the construction site, passed through Sanqiu, and transformed the old stone pond into a new one, forming a huge barrier in the north of the city. Its mezzanine pond is well designed and has a huge project, which is rare in Zhejiang coastal areas. It has not been overhauled for nearly a hundred years. It was not until the tenth year of Daoguang reign (1837) that it was repeatedly attacked by hurricanes and stormy waves, and it was renovated, rebuilt and strengthened several times. After liberation, Houhai seawall is still the key flood control facility in Zhenhai and Jiangbei areas, which was restored twice in 1957 and 1964. In the 1980s, in order to meet the needs of urban development and construction, two new ponds, Zhenbei and Ash Storage Yard, were built outside the pond. At this point, this stone "dragon", which has invested millions of workers and benefited the people for more than 800 years, has completed the historical mission of guarding the city and preventing floods.
