In the first three years of Emperor Zhang Hengzhang's founding (78 AD), he was born in a dilapidated bureaucratic family in Shiqiao Town, Xi'e County, Nanyang County (now Shiqiao Town, fifty miles north of Nanyang City, Henan Province). His grandfather, Zhang Kan, was a local official and served as the Taishou of Shu County and the Taishou of Yuyang. When Zhang Heng was a child, his family had declined, and sometimes he had to rely on the help of relatives and friends.

It was this kind of impoverished life that enabled him to come into contact with the working masses of the lower strata of society and some realities of production and life, which brought a positive impact on his later scientific creation. Zhang Heng is one of the representatives of the Hun Tian Theory in the middle of the Eastern Han Dynasty; He pointed out that the moon itself does not emit light, and that moonlight is actually a reflection of daylight; He also correctly explained the causes of lunar eclipses and recognized the infinity of the universe and the relationship between the speed of the planets and their proximity to the Earth.

Zhang Heng [1] observed and recorded 2,500 stars, created the world's first leaky armillary sphere that can perform celestial phenomena more accurately, the first instrument to test the first - the wind and ground motion instrument, and also manufactured a guide car, an automatic memory drum car, a wooden bird that flew several miles, and so on.

Zhang Heng is the author of a total of 32 scientific, philosophical, and literary works, including astronomical works such as "Lingxian" and "Lingxian Tu".

In order to commemorate Zhang Heng's achievements, people named a crater on the far side of the moon "Zhang Heng Crater", and the asteroid 1802 was named "Zhang Heng Asteroid".

Guo Moruo, a famous Chinese writer and historian in the 20th century, commented on Zhang Heng: "Such a well-rounded figure is rare in world history. ”
