Recently, some photos of Guizhou University teachers taking their elderly mothers to class in Weibo have aroused heated discussion. In the photo, the old man sits at the back of the classroom, sometimes taking a nap, and sometimes looking at the front. The teacher lectures on the platform, and the students listen as usual, which seems to be unaffected by the old people.

The reporter learned that this teacher is Hu Ming, an associate professor at the School of Economics of Guizhou University. The old man in the photo is his 85-year-old mother with Alzheimer's disease. At present, he only knows his son and never leaves him.
