Ruqing, Wu Changshuo, formerly known as Junqing, originally named Cangshi, was born in Anji, Zhejiang, and is commonly used in signatures (Anji Wucangshi).
Writing the year and month, signing the name and stamping the seal on the painting is called "money". Some inscriptions also record the place of birth, age, place of painting, etc. If the work is a gift, the recipient's name, title, greetings, modest words, etc. must also be written. The content and format vary widely.
Models, in addition to changes in fonts and font shapes, can be divided into two categories: (single style) and (double style).
1. Short payment: simply sign your name or year and month, no more than a cross.
2. Double style: that is, in addition to the single style, the name, title, official title, tribute and other words of the recipient of this work are added.

3. When signing the chess piece, there should be no free stamps on the left and right corners.
4. Rectangular, round or oblong seals cannot be placed on the lower corners of square seals. The square seal cannot be placed on the blank space at the top of the calligraphy and painting.
5. When inscribing Chinese paintings in a straight line, the characters at the end of each line should not be neatly aligned with the length of other lines.
