All that in his little living room, every day.

Hello. Could you tell me what 'all that' means in this context?
Thank you.



(The wall of the boy's living room is covered in family photos, but everyone in those pictures were dead from gas bombing on the Kurdish villages years ago. Only his aunt's left. Those ones in the pictures are all his aunt's family members.)
"Thousands and thousands of people were killed and most of them were women and children. Naazim said he saw one picture of a man sitting over the bodies of his wife and then children, all dead." He looks at me with his sad, dark eyes and I just stare back.

All that in his little living room, every day.

It means the man has all those photos of his family to think about. It's a small room crowded with photos, and every one of them is a sad memory.
