Houhaitang

On the northeast coast of Chengguan Town, jinzhenhai District, it starts from the foot of JINZI mountain in the East and extends to Jiaxie Pavilion in Yufan houtang in the northwest, with a total length of 4.8 km. In 897 (the fourth year of qianning in Tang Dynasty), the mud pond was built, and in 1189 (the 16th year of Chunxi in Southern Song Dynasty), the single-sided stone pond was built. In 1748 (the 13th year of Emperor Qianlong of Qing Dynasty), it took more than three years to repair. It was rebuilt in 1848. Pitang foundation is 9 feet wide and thick wooden piles are driven. The bottom of the pond is rammed with stone blocks, and the top piles are nailed. The top of the pond is crisscrossed with stones, and the back of the pond is rammed with thick soil, which can allow two horses to gallop. The existing section from jinzishan to Jiancheng stele Pavilion at the west end is about 1300 meters long, which is combined with the parapet of zhenhaiyuan county. The city and pond are integrated, and the height is 9.9 to 10.6 meters. It not only blocks the tide, but also resists the enemy of sea invasion. The stone pond is 1000 meters long from the Beiting of the built city to the highway to the port. In July 1981, it was listed as a key cultural security unit in the county. On December 12, 1989, it was listed as one of the coastal defense sites in zhenhaikou, a key cultural relic protection unit at the provincial level.

Houhaitang

The houhaitang, located in the north of Zhenhai city, Ningbo, Zhejiang Province, is a masterpiece of wisdom of the ancient working people. It starts from the foot of JINZI mountain, which faces Zhaobao mountain in the East, and ends at Jiaxie Pavilion in Yufan town in the West. The pond is 4.8 kilometers long, 3 meters wide and 9.9 to 10.6 meters high. From a distance, the stone seawall across it is like a silver dragon leaning on the shore of the East China Sea, with extraordinary momentum and grandeur.

Regional characteristics

Houhaitang used to be a barrier to protect the city from wind and water. It was built in the fourth year of qianning (897 A.D.) in Tang Dynasty and has a history of more than 1090 years. At that time, the earthen pond was built. In 1189, it was changed into a stone pond, but it still couldn't resist the impact of Hurricane waves and collapsed many times. In 1748, Wang Mengbi, the county magistrate of Qianlong County of the Qing Dynasty, in order to resist the invasion of the wind and tide, pleaded with the court for funding to build the pond. After extensive investigation, Wang county magistrate believed that "a single stone and thin soil can last forever", so he rebuilt 576.5 Zhang interlayer stone pond at fengtaoding, built 396 Zhang stone pond at the secondary section, built 51 Zhang stone pond, and built 810 Zhang stone pond outside and inside the collapsed city in the north. He came to the construction site to direct the construction. After three years, he built a new masonry pond instead of an old one, forming a huge barrier in the north of the city. The excellent design and huge engineering of the sandwich pond are rare in the coastal areas of Zhejiang Province. It has not been overhauled for nearly a hundred years. Since the 10th year of Daoguang (1837) of the Qing Dynasty, there have been many hurricanes and waves, and the earth and rock burst, so they had to be renovated, rebuilt and reinforced several times.

In 1918, Mr. Zhu Binsheng, a 59 year old journalist in Zhenhai, started dredging the Qianhe River and building the Zhenhai houhaitang in order to prevent the invasion of sea tide, improve water conservancy and develop agricultural production. He not only donated thousands of yuan, but also raised a lot of money from his fellow countrymen in Shanghai, so that the project started smoothly. During this period, Zhu Binsheng "in the morning and evening, personal monitoring, success, and recovery, stick faltering inspection, see each other and sigh. In 1919, the Civil Engineering Department of the Ministry of interior awarded the first prize of river engineering. In August 1923, Wangong pond (1020 feet of stone pond and 3400 feet of earth pond) was completed. Huang Qinglan, a British from the Chinese foreign relief association, Gan Fulu, a British from the tax department of Zhejiang customs, and Wang Yiting, Li Baoyu, Sheng Zhushu, Fu Xiaoan, and Xie Huichuang, who lived in various townships in Shanghai, visited the town to inspect the Tanggong. They sighed the hardships.

According to the new Annals of Zhenhai County in the Republic of China

Dongguan township has Qianda River, more than 3000 meters long, with thousands of hectares of farmland along the river for irrigation. The river is silted up and shallow. Many discussions have been made about dredging and treatment, but the cost is huge and the result is not satisfactory. In the Wu Wu and Xia dynasties, Dai Yunlai, a native of the city, initiated the first five thousand gold coins. Zhongyu also donated thousands of gold and raised more than 20000. That is to say, we should recruit workers to start dredging, work hard and finish in a few months. After dredging bailongyang River to pingshuiqiao River, chengxiahe River and hutanghe River, BEIXIANG water conservancy was completed. Dongmenpu is the confluence of the four townships. The project is as great as the back seawall. The seawall is the guarantee of the whole city, and the tremor of the wind and waves is in danger. In the spring of kuihai, many people talked about the cultivation and management, and raised countless funds. Fu Zong Yao Fu, a native of the city, was given a large sum of money by the Chinese foreign relief association. He pushed Zhong Yu to be his director. He raised money in the morning and night and monitored himself personally. After his success, he fell ill again. The staff faltered and continued to patrol, and those who saw it sighed. In July and August of this year, there was a great hurricane, which destroyed countless things. The work of the pond remained intact, and the effect of solid work was more and more obvious.

After liberation, houhaitang was still a key flood control facility in Zhenhai and Jiangbei areas. It was repaired twice in 1957 and 1964. In the 1980s, due to the needs of urban development and construction, two new ponds, Zhenbei and Huiku, were built outside the pond. So far, the stone "dragon", which has been working for millions and benefiting the people for more than 800 years, has completed its historical mission of defending the city against flood.

Today, this stone pond, which embodies the hardworking wisdom and strength of the ancient working people, has become a patriotic education base in Ningbo, a tourist attraction for guests at home and abroad, and a new place for people to rest and play after dinner. In the early morning, it is a good place for morning exercise because of the misty haze and the same color of heaven and earth. In the evening, the lights are flashing and a scene of prosperity is seen. It is the flames from the chimneys of the oil refining workshop of Zhejiang Zhenhai Petroleum Refining and Chemical Corporation jumping. When you stroll along the end of Chenghe East Road, the busiest part of Zhenhai District, and look north at the seawall along the ring road, the first thing you can see is the foot of JINZI mountain, which faces Zhaobao mountain. JINZI mountain is "towering in shape, like a towel". You come to the foot of the mountain, climb up the steps, and climb to the top of the mountain, where the cool sea breeze comes. Looking from afar, there are rows of houses and buildings in the pond. Outside the pond, there used to be endless tidal flats, which is a new area under development in zhenhaikou. Walking east and west along the body of the pond, the water of the city protection under the pond is sparkling, and the newly planted oleander and peach trees on the pond are green and green. You will never forget to return when you are in this situation.

Tourism characteristics

If you look carefully, you will find traces of two blockhouses half hidden underground in the middle and west of Shitang, which is a historical witness of Zhenhai people's resistance to Japanese invasion. There is a pavilion at the East and West ends of the stone pond. In ancient times, there were eight buildings on the eastern head of JINZI mountain, which were the place for officials to chant poems and drink banquets. Today, it has been transformed into a stone pavilion imitating the Ming Dynasty, with a built-in memorial to Zhang Shijie and a memorial to the ancestral hall of Zhang Taifu written by Quan Zuwang. It is said that in 1276, when the yuan army approached Lin'an (now Hangzhou), song general Zhang Shijie moved his army to Zhenhai. Bian Biao, the capital of the Yuan Dynasty, was ordered to come to surrender. Zhang Shijie was so angry that he broke his tongue and sentenced him to punishment. There are many poems praising this. Ming Lin Shiyao's poem "mountaineering diaoyue Gong" says: "the lonely minister ' The western end of the pond is jiaxieting. The stele inside the pavilion records the long history of local people building the pond around the sea for thousands of years.
