But Zhang's adjutant should be younger than Zhang, and he was kicked out of Zhang's family from birth because he didn't have pure Kirin blood.
After Zhang Qishan established himself in Changsha, he returned to Zhang Gulou to visit relatives, only to find that the Zhang family had already left this Gu Lou and went to Jilin for generations.
Zhang, the adjutant, was still young and was rescued because of the collapse of Zhang's forces. Zhang Qishan saved them and established Zhang Jiajun. It is the pro-corps of Buddha Zhang. So in fact, Zhang Rishan grew up in Jilin, and Zhang Qishan knew that Zhangjialou was in the northeast. This family has been well hidden for generations, and it is reasonable that Zhang Rishan can't find it.
