Why are there two doorplates hanging in the pavilion?

If the whole is a big plaque, it will be easier. The construction team will install scaffolding at your door first. Adjust it to a suitable height, and then hang the plaque on the scaffold. On the wall of your door, they have fixed it. Then put the plaque on the fixed bracket that has been made. Fix it. We can often see some newly opened shops. Their plaque will cover the first one or two with red cloth. This is a homonym for good luck. The meaning is similar to that of Hongyun.
