Write! The signature of China's calligraphy is also divided into single paragraph and double paragraph. Your signature should be the next paragraph of a single paragraph or a double paragraph, including time and place, author's name, font size, etc. And sometimes you have to write down the source of the text, the object of gift, the reason for creation, and so on. It's just a development process. For example, the famous Preface to Lanting and Fu on the Red Wall are not inscribed, but the first sentence of the text points out the time. Later, it was gradually standardized. Basically, the name and date were written vertically on the left side, indicating the giver and the recipient when giving gifts, and some exceptions were not excluded ~
