Okay, so you know how you have a house that you live in with your family? Well, a long, long time ago, there was a man in China who was very important and powerful. He was called the Huangcheng Chancellor. He had a big house where he lived and did his important work.
Now, this house was not like your house or my house. It was very fancy and grand. It had many rooms and lots of decorations. People who visited the Huangcheng Chancellor were always impressed by how beautiful his house was.
The house was also very important because it was a symbol of the Huangcheng Chancellor's power and status. People knew that if they wanted to talk to the Huangcheng Chancellor about important things, they had to go to his house.
Unfortunately, the house doesn't exist anymore because it was a very long time ago and things can get old and fall apart. But we still remember it because it was an important part of China's history.
