Can Guo Bo bring his own book with a seal?

The National Museum allows visitors to bring their own cards or paper for stamping. Visitors can prepare their own cards or paper, use special printing paper to unlock the stamping machine, and even attach extra stamps. This regulation provides tourists with more flexibility and personalized choices, and can record their own experiences in Guo Bo. Visitors can freely choose the style and material of the card and record what they are interested in.
