Rarely write on portraits. Occasionally writing: "portrait of Comrade XXX" is also very simple. There is a memorial tablet with a one-inch photo on it, which is written like this. Like couplets, they were born on a certain day and died on a certain day, with the words "my father's post" written vertically in the middle. Some exquisite people really write couplets instead of dates of birth. For example, Zangtou's couplet, "Hu Qi inherits Gao Fu with a cloud crane and benevolence, and Gong Hong rhymes with a chapter to cast a good name", is a celebrity named Qi Gong.
