As long as you work hard enough, an iron pestle can be ground into a needle!" is my favorite famous saying. Its origin is also related to a story. It is said that Li Bai was studying in the Elephant Er Mountain, but before he could complete his studies, he gave up, " Crossing the stream, I met an old woman who was grinding an iron pestle, and asked her, "I want to make a needle." Taibai realized what he meant and graduated." This famous saying tells me a truth: Although the iron pestle is big and thick, it can be ground into a needle. The needle is very difficult, but as long as you work hard and have perseverance, day after day, year after year, the iron pestle can be ground into an embroidery needle. In fact, it is the same when we study, and we will eventually encounter When encountering some difficulties, we should persevere and not stop halfway. Then, no matter how big the difficulty is, we will definitely overcome it!
