What warm-hearted things have you encountered during your trip?

I was abandoned by an old man on the bus in Hangzhou. At that time, there was no subway in Hangzhou, so we had to change to another hotel to take the bus, carrying bags and suitcases, and having no seats. Holding the railing to take care of the suitcase is inevitable. An old woman next to her suddenly stood up. "Little girl, come and sit here." I thought she was going to get off and sit down, but after two stops, she hasn't got off yet, so I can't sit still. I wanted to give her my seat back, but she said nothing. "You take yours, I didn't bring anything." Now every time I see the news that old people touch porcelain to grab seats, I think, not all old people are bad people, but there are many good people.
