The elderly, especially those in rural areas, rarely have their pictures taken due to the absence of more advanced technology. Most of them still use cellphones without cameras.

"When elders pass away in our village, either they have no photo like my grandpa, or they have to use the one from their ID card," Wu said.

When Wu's grandma asked him to take a funeral portrait for her, he was a little upset.

"It was as if she was getting ready for the end," Wu said.

However, when he saw her getting excited while picking out the outfit for the photo shoot, he changed his mind and began to feel that a well-taken photo was better than none.

Wu helped dye his grandmother's hair and found a piece of red cloth for the backdrop.
