Fusu

Fusu (died c.August or September 210 BC^[1]) was the eldest son and heir apparent of Qin Shi Huang, the First Emperor of the Qin dynasty.

^ Vol.7 of Zizhi Tongjian indicate that Qin Shi Huang died on the bing'yin day of the 7th month of the 37th year of his reign. While there was no bing'yin (丙寅) day in that month, there is a bing'shen (丙申) day, which corresponds to 11 Aug 210 BCE in the proleptic Julian calendar. The same volume also indicate that Qin Shi Huang was buried in the 9th month of that year, which corresponds to 19 Sep to 18 Oct 210 BCE in the proleptic Julian calendar. Since Fusu definitely died after his father and likely before the emperor was buried, Fusu's death should be in Aug or Sep 210 BCE.
