Meritnation experts kindly explain me this whole paragraph in a sheet of paper i am struggling and unable to understand i need handwritten explanation

Dear Student,

In the chapter 'A House is not a Home', when Zan's house caught fire, his mother rushed back into the house to get important documents and old pictures of her husband. Zan's father had died when he was young and his mother wanted to save some of his memories. Zan tried to run after her but the firefighters helped in rescuing his mother.

Regards
