Introduction to Zhu Zaiyu:

Zhu Zaiyu (1536—161year), male, born in Jiufeng Mountain, Qushan. When he was young, he was called "Crazy Life" and "Yang Shan Drunken Xianke", also known as "Duanqing Shizi", who was born in Hanoi County, Huaiqing Prefecture, Henan Province.

1536, Zhu Zaiyu was born in Hanoi county, Huaiqing prefecture, Henan province. He was the ninth grandson of Ming Taizu and the fifth son of Zheng Fan in the Ming Dynasty. Zhu Zaiyu was deeply influenced by his father, Gong Zheng Wang Xiude. He could give lectures, dress and grow vegetables, read and write, and was a thrifty and studious person since he was a child. In his early years, he studied astronomy, arithmetic and other knowledge from his great-uncle He Tang. He was imprisoned for the unjust conviction of his father and lived alone 19 years. It was not until 1567 that his father was pardoned that he was willing to enter the palace.

159 1 year, Zheng Wang Zhu Houan passed away. As the eldest son, Zhu Zaiyu should have succeeded to the throne, but he resigned and returned home to concentrate on writing. In the long years of 19, Zhu Zaiyu worshipped Tessa, went out of common sense, pursued the spirit of the sun and the moon, devoted himself to the study of temperament and calendar calculation, and opened up a broad frontier subject field.

Zhu Zaiyu went beyond the rules of his ancestors, broke away from old habits, paid attention to practice and experiment, and worked hard to seek truth all his life. He completed the Complete Book of Rites and Laws, Law and Theory, Doubts and Doubts between Law and Lu, Jia Jing, Essentials of Law and Lu, Integration of Law and Calendar, New Theory of Arithmetic, Atlas and so on. His achievements shocked the world, and Chinese and foreign scholars honored him as "the saint of the Oriental Renaissance".

Therefore, Zhu Zaiyu and Guo Moruo are listed as "world historical and cultural celebrities" together. Zhu Zaiyu is a native of Hanoi County, Huaiqing Prefecture, Henan Province (now Qinyang, Henan Province). His father, Gong Zheng Wang Zhu Houan, is good at writing and proficient in music. Zaizhen was deeply influenced since childhood. He likes music and math, and he is also very smart.

Europeans are appreciating and practicing Zhu Zaiyu's inventions, but in China, Zhu Zaiyu's hometown, his creations have been shelved. After sleeping for more than 400 years, Zhu Zaiyu is still lying in the scholar's study, although he has been re-recognized and studied.

Open any history textbook, whether it is primary school or middle school, it is easy to see the achievements of Li Shizhen, Song, Xu Guangqi and Xu Xiake, but it is difficult to find the name of Zhu Zaiyu. As Dr. Needham said, "This is an incredible irony."
