When I was in primary school, our school was engaged in a one-on-one counterpart poverty alleviation program. The plan is to help a brother primary school in a mountainous area and donate money and materials every year. Very lively. The teacher also carried out a one-on-one assistance program, and each child wrote to a child from the other poor school. This aid project has been going on for about a year. Twenty years later, I met my husband in a coincidence place. I accidentally talked about my childhood after marriage. We were surprised to find that his primary school was the poor primary school that our school helped 20 years ago. You guessed it, the child who keeps a short correspondence with me is him.
