King Xiaowen of Qin (302–250 BC), personal name Ying Zhu or Ying Shi, was a king of the Qin state.
He is also known as Lord Anguo (安國君), based on his title before his kingship.
He was a king of the Qin for less than one year, and died three days after his coronation.
The most accepted theory is that he was very old when he ascended to the throne (his father ruled for over 50 years).
This is supported in a way by the fact that Zhuangxiang reigned for only 3 years.
