Wang Xianzhi was proud of his good handwriting when he was a child. One day, Wang Xianzhi wrote a word "big" to his father Wang Xizhi. After reading it, Wang Xizhi added a little without saying anything, and the big characters became too big. Wang Xianzhi went to show his mother the word "Tai" again, and her mother said it was just like what your father wrote. Wang Xianzhi felt very ashamed. He understood the gap between himself and his father. He went to ask his father the secret of writing well. Wang Xizhi told him that he would know as long as he finished writing the water in the back garden 18 large water tanks. Finally, Wang Xianzhi became a great calligrapher.
This story tells us that there is no shortcut to learning, and only persistent efforts are the secret of success.
