The "gold brick" floor of the Forbidden City and The "cat security guard" of the Forbidden City

The "gold brick" floor of the Forbidden City
The floor of the Forbidden City is not a real gold brick, but a special brick called "gold brick". This brick is produced in Suzhou, and the production process is extremely complicated. It is fired through multiple processes. It makes a metallic sound when knocked, so it is called "gold brick".
The "cat security guard" of the Forbidden City
Today, there are many stray cats living in the Forbidden City, and they are called "Forbidden City cats". These cats not only add fun to tourists, but also take on the responsibility of "security", helping to drive away mice and protect ancient buildings from rodents.
