Tu Lihua, a resident in the city of Wuhan took photos of the people she felt grateful to, as a return gift to say thank you.
She said the figures in the photos are those who offered their seats to her when she took public transport.
"People often offered seats to me when seeing an elderly passenger like me, but I always felt uncomfortable in such a case, asking myself why should they give their seats to me. After I got this handset, I thought of taking a picture of each of them as my gratitude, and there may be a chance to use them as commendation."
Tu started to take pictures of those tender-hearted young people with a smartphone, beginning in May 2014 and put them in a computer file.
In the beginning, not many people understood her intention and refused her request for a picture. But after explanation, people started to accept.
"Once there was a girl who didn't agree at first but after I showed her my pictures, she agreed then."
Tu cited a young woman that impressed her most.
"I told her that I wanted to take a picture of her. She was a little shy, but agreed. Then she said, 'Granny, you are fun, and I want to have a photo with you too."
She added that it's the first time that she took a selfie.
Tu said that if she has to go out, she tries to avoid rush hours in the morning and evening. She said that the young people live a busy life and would be tired after a day's work.
She said that there are more people who give their seats to her. The pictures only account for a small number of them.
After the pictures became popular on the internet, Tu would sometimes check the comments.
"Someone leaves a message saying that those in the pictures are all good-looking. Men are handsome and girls beautiful. Someone answered, 'That's right, the looks are usually reflections of the hearts'."
Tu said that she will continue to record those who help her as a way to show her gratitude.
