Which link in the revival of UnionPay poetry POS machine touched you the most?

What moved me most in the revival of UnionPay poetry POS machine was that at the scene where Xiaoyu met his mother, the train volunteers sang the theme song of UnionPay poetry POS machine adapted from children's poems-"Growing Secretly" to help children pass on their dreams through singing. What moved me was not only the song, but also the volunteers. In our daily life, in fact, we can come into contact with these contents more or less, but many of us can't let go of our present material life and excellent living conditions, while those volunteers can give up their original lives and resolutely go to the mountainous areas to participate in teaching work. This is what I admire very much. "I don't need you to return anything. I hope that you can pass on your love and care to more people in need in the future. " I hope I can be full of courage in the future and pass on my love and warmth. I also hope that more people will use UnionPay POS machines to convey this love.
