This is a portrait of a person. There are two figures in costume standing in the painting. The taller one should be Yin Zhen, Yong Zhengdi of the Qing Dynasty (Sejong of the Qing Dynasty), and the shorter one should be the future emperor Qianlong (Emperor Gaozong of the Qing Dynasty), both of whom are wearing Hanfu. There is no seal of the author on this painting, but there is a poem written by Emperor Qianlong above it: "I am good at taking pictures of Shi Ning. When I was a teenager, I didn't know who this was. " The title of Spring is awkward. "This poem was inscribed in the forty-seventh year of Qianlong (1782), when Emperor Qianlong was 72 years old. This poem reflects his feelings about the passage of time.

In addition, there are two seals on the painting, namely "the ancient emperor", and there are three seals from right to left at the top of the picture, namely "the treasure of the emperor's father", "the ancient emperor" and "the treasure of the eight diagrams palm memory".

It's Yong Zhengdi and Prince Li Hong. Their postures and forms, especially the faces of the characters, are very delicate. Basically, the lines depicting the outline are invisible, but the three-dimensional effect of the five senses is expressed by the depth of the color. It can be seen at a glance that it is different from the traditional "photographing" technique in China, with strong traces of European painting. "A Spring Letter of Peace" can be confirmed to be written by Italian painter Lang Shining.
