田令孜
It is not known when Chen Jingxuan was born. According to the "Zizhi Tongjian", his family was from Xu Prefecture (許州, in modern Xuchang, Henan). He had at least two younger brothers, Chen Jingxun (陳敬珣) and one other who later became known as Tian Lingzi—as that younger brother became a eunuch in his young age and was adopted by a eunuch named Tian. He probably had two older brothers, as, at one point, Tian Lingzi referred to him as the third brother.
