Qin Shi Huang's daughter, Ying Yinyan, the cause of her death remains a mystery. This historical mystery requires more in-depth research before it can be revealed. The history books have two very different versions of the cause of Ying Yinyan's death.
First of all, there is an opinion that Ying Yin Yan may have died in the tricks of fate. According to historical records, Ying Yinyan's mother was Lü Buwei's concubine, and because of her embarrassing status, she was regarded as a political bargaining chip and was forced to marry away from home. During this distant journey, Ying Yinyan may have encountered an unforeseen accident that led to her untimely death.
On the other hand, the cause of Ying Yinyan's death may also be related to the power dispute in the court. After Qin Shi Huang unified the Six Kingdoms, he took extreme measures against the descendants of the nobles of the Six Kingdoms and eradicated them. And Ying Yinyan, as the daughter of Qin Shi Huang, may have fallen victim to this political storm. Perhaps she was embroiled in a power struggle within the court and was eventually assassinated.
However, these claims are not supported by conclusive evidence, so we cannot determine the true cause of Ying's death. As the daughter of Qin Shi Huang, her fate was bumpy, and the cause of her death was a mystery. Perhaps, historians need to dig deeper to unravel this ancient mystery over time.
