As the name implies, the riding seal is to press the edge seam when stamping, and the common official seal requires "riding the moon in the year".

However, the riding seal requires "riding seam", that is, the official seal should be evenly covered on the middle seam of two sheets of foldable paper, half of which should be kept as a stub and the other half as a voucher. When verifying, the two halves should be completely integrated with the official seal.

Only one page is needed for a 2-page riding seal, and 2 pages is the minimum number of pages to cover the riding seal. The two-page riding seal is easy to cover, the paper is spread neatly along the seam, and the stamps are evenly distributed on two pieces of paper.
