According to Chen Xin's original plan, the two brothers Han Ping and Han Ze also lived in the lower rooms of the refuge.
But as the elder brother, Han Ping expressed a desire to live with his brother at the entrance on the upper level, serving as gatekeepers and guards after understanding the structure of Chen Xin's refuge in detail.
"Mr. Chen, if everyone lives underground, in the event that something happens above, it might be too late to come up. So, it's better to have a post at the entrance to respond promptly in case of any incident."
These were Han Ping's exact words, and after giving it some thought, Chen Xin decided to agree with his reasoning.
While allowing Han Ping and Han Ze to live as gatekeepers on the upper layer, Chen Xin also modified the observation room to add a bedroom for the two brothers.
