In the west side of Baoding Water Conservancy Museum on Xinghua Road, Baoding, there is also an ancient building that is the Baoding Huaijun Mansion, the full name is "Baoding Huaijun Zhaozhong Ancestral Hall and Office", it is Li Hongzhang when he was the governor of Zhili and the minister of Beiyang, and the Qing Dynasty Hui School ancestral hall style building complex built by the edict to integrate the functions of sacrifice, office and guild hall. This public office is the fifth Huaijun Zhaozhong Temple built to commemorate the soldiers who died on the battlefield, and it is also the only building where the Zhaozhong Temple and the public office are combined. The ancestral hall is the fourth "Zhaozhong Temple" built after Suzhou, Wuxi and Wuhan to commemorate the Huai soldiers who died in the battle, with public sacrifices, garrison organs, and the function of Anhui guild hall. In the twenty-eighth year of Guangxu of the Qing Dynasty (1902), the Qing court issued a special decree to change the building on the central axis of the Zhaozhong Temple to "Li Wenzhong Ancestral Hall", that is, Li Hongzhang Xiangtang.
Li Hongzhang was born on February 15, 1823 in a farming and reading family in Modian Township, Hefei County, Luzhou Prefecture, Anhui Province. His name was given by his father, Li Wen'an, and since the Li branch was previously inherited from the Xu family, there was no genealogy at first. It was not until the Jiaqing period that the "Li Family Genealogy" was compiled for the first time, and the 16-character ranking was agreed, that is, "the article is through the country, the family road is Yongchang, the blessing is longevity, and the honor is enjoyed by the world." Later, 16 characters were added, which were: "Zude accumulates thickness, Keshao glow, Zongxu extends, and Tongdun filial piety." Li Hongzhang is a chapter generation, his father Li Wenan is a bit unconventional, he has 6 sons in his life, in addition to the real name of "Li Zhang X" or something, there is also another name that puts the word "chapter" at the end. The second Li Hongzhang, whose real name is Li Zhangtong. Although Li Hongzhang is the character of the Li family, the chapter character is in the third character, and the name alone cannot see the chapter character generation.
