Bibliographer and calligrapher in Qing Dynasty. Nice handwriting. It's called Luyuan. Hou Guan (now Fuzhou, Fujian) was born. In the thirty-eighth year of Kangxi (1699), he was promoted to the township entrance examination, and in the fifty-first year (17 12), he was awarded the scholar and cabinet book. He takes poetry as his profession, is familiar with calligraphy, and is good at small letters and official scripts. Wang Wan is a teacher, and Chen Tingjing and Wang Shizhen are the themes of poetry. He copied Wang Wan's Yao Feng Wen Copy, Chen Tingjing's Wu Ting Wen Bian, Wang Shizhen's Yu Yangshan Tale of Talents, Gu Fu's Yu Ting Draft and other books by hand. Its calligraphy strokes are simple and mellow, and its seal cutting style is called "Lin No.4" by calligraphers and collectors. This family is very rich. The library building is called "Pu Xuezhai", which is a rare and precious book. Xu Gan's academic journals Tongzhitang Jingjie and Zhu Yizun's Poems of the Ming Dynasty all borrowed his books and copied them in many places. I love books all my life until I die. In his later years, he received 50 kinds of suicide notes from the famous bibliophile Xu Huobo, claiming that "Confucianism is purchased first, regardless of ten thousand volumes, which is similar to Xu's time in Aofeng." The collection is printed with the words of Changlin, Ji Zhi, De, Chen Ji's seal and other Zhu, and written with the draft of Park Xuezhai and Park Xuezhai's note.
