The original text, Wen Zhengming, was writing the "Thousand-Character Essay" shortly, with ten copies a day at the beginning, and the book progressed greatly. Throughout my life, I have never been sloppy in writing, or answered people's simple notes, rarely paying attention, but I will never tire of changing them over and over again, so the older I get, the more sophisticated they become.
The translator Wen Zhengming supervised the writing of "Wenwen", and he wrote ten books every day as a standard, and his calligraphy improved rapidly. He has never been careless about writing in his life. Sometimes when someone replies to a letter and it's a little bit incomplete, I must rewrite it over and over again without fear of trouble. Therefore, his calligraphy became more exquisite and beautiful as he got older.
