Sun Feihu, a "post-80s" who grew up at the foot of Tianmu Mountain, has spent more than a decade using his leisure time to search for and collect local historical materials in Lin'an.

Some people say that Sun Feihu is like a textile craftsman who threads needles and threads, stitches and stitches local historical materials with strong nostalgia, and re-presents the history of local development in front of people's eyes in the form of pictures and texts.

Just past the Qingming holiday, Sun Feihu found a hundred-year-old plaque, and his heart was very excited, giving a high evaluation - "This is the most precious of my thousands of local historical materials." ”

Can't help but wonder, who is the owner of this plaque, and what kind of story is behind it?

A century-old plaque, from whom?

During this year's Qingming holiday, a friend from Sun Feihu's collection circle in Anhui inadvertently mentioned that he saw a plaque in the local area, which was written by Fang Keyu. The three words "Fang Keyu" have long been engraved in Sun Feihu's mind, and among the historical materials he collected from Lin'an Yuqian Xiangxian, there are both Jin shihong's "Pingzhai Anthology", Xie Yuanwu Hanfen's "Reading Pleasure", and the poet monk Dao Qian's "Collection of Samsonzi Poems", but the historical materials of this geometric master are lacking.

Who is Fang Keyi? Lin'an Yu Qianfang yuanren, a famous mathematician in the late Qing Dynasty. In 1890, the 20-year-old Fang Keyu went to Beijing to participate in the examination, and was born in the second class, becoming the last Keju Jinshi in Yu Qian, serving as the head of the Punishment Department. In 1896, he became prime minister of state affairs. After the Eight-Power Coalition invaded Beijing in 1900, Fang Keyu participated in peace talks as an attaché. (The story of Fang Keyu, see "Meet Han Qian Tang Chang| Fang Keyu, not just a mathematician)

In addition to serving as an official, Fang Keyu never stopped his exploration of mathematics, and his authors such as "Curve Examination", "Eight-Line Method", "Tetralogy Technique" and so on were engraved as "Fang Zizhuang Mathematics", as well as "Conical Curve Theory", "Sharp Cone Technique Solution", "Sharp Cone Technique", "Triangle Formula", "Pythagorean Formula", "Firearm True Recipe", etc.

When Sun Feihu heard this, he was very excited in his heart, so he asked his friends to go to confirm.

The plaque that the friend said was now idle in the miscellaneous room of an old house in the countryside of Shexian County, Anhui Province, full of dust.

Unveil the newspaper on the plaque and carefully examine the money on the left side: Zhi Jinshi's Origin The Hand-picked Governor specially awarded Guizhou Sifang Keyou Prayer Title The Twenty Years of Guangxu of the Great Qing Dynasty.

"Now the official position of Fang Keyu on the Internet is that he once served as the chief of the Punishment Department, but only in the Guangxu edition of the "Yu qianxian Chronicle" is introduced in more detail." The three words "Guizhou Division" in the county chronicle jumped on the paper. Sun Feihu was convinced, yes, it was Fang Keyu.

According to the excitement in his heart, Sun Feihu bought the plaque and asked his friends to transport it back to Hangzhou from Anhui on the second day of the holiday.

Why does Fang Keyou's plaque appear in Anhui?

Behind each plaque, there is a story.

This is a birthday plaque. The plaque is about 1.68 meters long and 0.63 meters wide, made of beech wood. After a hundred years, although some of the mold has turned black, the four golden characters of "A Full Flower Age" are still clearly recognizable under the background of black.

"I am over sixty years old, but I am as young and healthy as the age of the flower season." The interpretation of the four words expresses the good wishes of the person with the inscription for the health and longevity of the owner of the plaque.

Why does this birthday plaque appear in Anhui, 150 kilometers away? There were doubts in the hearts of the people.

The inscription on the zhushou plaque is in the twentieth year of Guangxu in the Qing Dynasty, which is the fourth year of Fang Keyu's examination for the Jinshi. Sun Feihu after understanding, the owner of this plaque zu Shang was also an official, perhaps, more than 100 years ago with Fang Keyu in the same dynasty as an official, perhaps, and Fang Keyu is a like-minded close friend, Sun Feihu analyzed, Xu was the old man in the other party's family at that time, Fang Keyou personally inscribed the plaque to send, this possibility exists.

One plaque inscribes the past of time, the good wishes promised, the virtues of respecting the elderly, passing through ancient and modern times, forming a story and telling future generations.

Looking at this birthday plaque in front of him, Sun Feihu's heart could not help but sigh, this may be the only plaque inscribed by Fang Keyu himself.

In 1907, Fang Keyu died of overwork at the age of 38 and was buried in Qianfangyuan Village. In 2019, Ms. Fang Meiqing, the granddaughter of Fang Keyu and 93 years old, rushed to Lin'an with her children and donated 10 Fang Keyu manuscripts to the Lin'an Museum on behalf of the Fang clan. "Fang Keyi left very few manuscripts and published books, and the plaque with his inscription had not appeared before."

Ten years of searching for the road, guarding is more difficult

"This is the most precious of the more than 1,000 pieces of local historical materials in my collection in the past 10 years."

The reason why Sun Feihu gave such a high evaluation is that in his opinion, this plaque is not only an important proof of the study of literary and historical materials, but also has high artistic value and historical value.

After the excited heart gradually calmed down, there was still a difficult problem in front of Sun Feihu.

After a hundred years, the plaque has been seriously damaged, and there have been many molds, insects and moths, coupled with accidental bumps during transportation, resulting in secondary damage to the plaque.

After Sun Feihu got the plaque, he carefully cleaned it up, then packaged it, and did not dare to "act rashly", "After all, after a hundred years, the wood has been very brittle, for fear of a careless, let it hurt again." ”

How can it be saved in the future? This question has always haunted Sun Feihu's mind, "Only by protecting it well is the best comfort for this honest and honest village sage." ”

Sun Feihu hopes to repair the plaque and preserve it better, but repairing the plaque is not an easy task, and if you are not careful, you will lose its "original taste". To this end, he consulted many friends in the circle.

In fact, this is also a problem that Sun Feihu often encounters in the process of collecting.

Thousands of yellowed local documents such as the "Fish Scale Atlas" of Changhua County in the fourth year of the Kangxi Dynasty of the Qing Dynasty, the "Record of The Reconstruction of the Qianwang Ancestral Hall" in Lin'an County in the eighth year of the Republic of China, the "Nationalities Daily" in Qianxian during the War of Resistance Against Japanese Aggression, and the progressive books published by the Yegong Bookstore (Wang Yegeng Martyr) in Changhua County in 1949... In the past ten years, Sun Feihu has carefully collected historical fragments of Lin'an City, and nearly a thousand pieces of valuable and valuable local historical materials have been preserved through various channels, leaving precious historical memories for the place, "Every yellowed piece of paper is a story of salvation." ”

But the road to protection is more difficult. Sun Feihu said that ten years of searching for the road of protection, let him more deeply appreciate that the fate between collectors and collections needs to go through the polishing of time, sometimes passing by, sometimes unexpectedly, as the inheritor of the culture of the new era, while appreciating the beautiful countryside and the butterfly changes of the charming city, we need to constantly adhere to and guard the memory of local historical changes.
