When was Jia Baoyu born?

Starting from the major doubts and clues revealed in the novel text, using the calendar data and combining with the history of the decline and fall of the Cao Shi family, the real time of death is determined to be the year of Guimao after "beginning of spring on December 29th" (1723 first year of Yongzheng); The eight-character numerology was used to determine the date of birth as the time of Xinhai (1February 692 18). Taking the time of Yuan Fei's death as a fixed time coordinate, the real year of Jia Baoyu's birth is 1706 Xu Bingnian.

According to the three characteristic times of "Dragon Boat Festival is in summer to the day after", "Light Snow Festival is in the middle of October" and the day after December 29th of that year is the first day of the first month, it is inferred that Jia Baoyu 17 19 is the year of his own life, and it is further confirmed that Jia Baoyu was born in 1706. Through the analysis of "the mango seeds crossed in the evening of April 26th", it is determined that this characteristic time was changed from "the mango seeds crossed in the evening of April 26th" in Xu Bing1706.

Zhou, a famous red scientist, demonstrated Jia Baoyu's birthday. Because of Zhou's unshakable position in A Dream of Red Mansions, his argument about Jia Baoyu's birthday has deeply influenced many people. Whether Zhou's conclusion is April 26 or the exact date of "the birthday of the medicine king" is April 28, a series of speculations about Jia Baoyu's birthday in late April have been formed.
