There are always lucky people and unfortunate people in a society. Lucky people have the responsibility to care about unfortunate people, pay attention to their fate, let them live a good life and help improve their situation. In retrospect, the author was ashamed of not paying enough attention to Lao Wang. The author has the concept of equality, humanity and kindness. Because the author is an intellectual, she is educated, and she knows the responsibility of an intellectual-to help the weak and unfortunate with her greatest strength. This is not the realm that can be achieved by "rolling in the mud" in rural factories. Another point is that over the years, few people have said a lot of empty words, but how many people really sympathize with and care about an unfortunate weak person-more importantly, treat each other as friends and sincerely understand and communicate? This is rare, including the author's own failure to do it completely, so she feels ashamed. The author's profound reflection is also the valuable part of the article: it has a strong humanitarian spirit.
