Pei Xiu
It is not known when Pei Che was born. He was from The Eastern Juan Pei of Pei clan of Hedong. His grandfather Pei Su (裴肅) served as a governor during the reign of Emperor Dezong, and his father Pei Qiu (裴俅), a younger brother of Pei Xiu, who served as a chancellor during the reign of Emperor Xuānzong, served as an advisory official. However, while Pei Qiu was referred to in Pei Xiu's biographies in the "Old Book of Tang" and the "New Book of Tang", no reference was made to Pei Che, perhaps because of Pei Che's eventual end.
