A photo of a young Chinese boy, who helped not only his own mom but also someone else’s on the subway, has gone viral.

The picture was taken on a train in Chengdu, China, and it shows the boy leaning on the rail, using one of his hands as a pillow for his mom’s head while she sleeps, Nextshark reports.

A straphanger who saw the heartwarming gesture told Shanghaiist that the boy initially sat by his mom, but then offered his seat to another mom with a baby stroller.

The image was posted on Chinese blogging site Weibo, and has since garnered more than 180,000 likes and 18,000 comments.

One Weibo user wrote, “Help me ask around about who this kid’s parents are. I want to go ahead and arrange for him to marry my future daughter.”
