The earliest record of Halley's Comet recognized in the world appeared in Biography of Qin Shihuang. In the seventh year of King Qin (240 BC), the amazing discovery that "comets shine in the east and see the north, see the west in May and see the west again" was 228 years earlier than the earliest comet record in the west.

Until 19 10, Halley's comet appeared 29 times with a period of 76 years, which was recorded in the history books of China, and even in the Book of Jin explained why the comet shone.

Extended data:

After the Song and Yuan Dynasties, the ancients observed Halley's comet more and more accurately and recorded it in more and more detail. For example, westerners Appiannis, Kepler and Haley observed Halley's comet three times, which are recorded in detail in books such as Ming History, Qing History Draft and Donghua Record.

Although China people first discovered Halley's Comet and recorded it in detail, due to the limitation of historical conditions, they did not grasp its operation law and predict its reappearance time. Harley, a famous British astronomer, realized this.
