Ni Yuanlu (1593 ~ 1644), whose name was Ruyu, was Hongbao, a No.1 garden guest, and his ancestral home was Shangyu (now Zhejiang). He was brilliant since he was a child. At the age of seven, he was able to compose poems. When he came to Yunjian at the age of 19, Chen Jiru was quite amazed and called him a "fairy talent". In the second year of the Apocalypse (1622), he was a scholar for Jishi Shu, and later moved to Guozi to offer a drink. Hou Fangyu was his protege. In the first year of Chongzhen, he neglected and lashed the eunuch. Later, because of the jealousy of the records, he left his job at home. In the fifteenth year of the Apocalypse, he was appointed as the right assistant minister of the Ministry of War, and the following year, he was appointed as the minister of the Ministry of Housing and a bachelor's degree in the Imperial Academy. Li Zicheng conquered Beijing and Yuan Lu hanged himself. Ni Yuanlu is good at running script and cursive script. Ni Yuanlu's calligraphy not only has a strong and simple style, but also has the characteristics of the Ming Dynasty's fluent calligraphy in beautiful and elegant. It comes from the calligraphy of Tiexue, and also has the characteristics of tablet calligraphy, especially in the Six Dynasties. Ni Yuanlu and Huang Daozhou joined the ci circle at the same time, and became friends. Both of them were concerned about the country and the people, encouraged each other with honor, and wrote books in the Hanlin Academy. Therefore, Ni Yuanlu's calligraphy and painting are as famous as Huang Daozhou's, and they are called "Huang Ni".
