What are the dimensions of the screen wall and the door?

Do you mean how far the screen wall is from the door? There is usually a shadow wall 2-2.5 meters away from the gate, which can divide the space at the entrance and block the line of sight.

Not too high or too wide, the width can block the view of the courtyard, because the shadow wall is very close to the human scale, and there should be detailed things to see on the wall, such as murals and brick carvings. The screen wall can decorate the facade, so that people who enter and leave the gate can see auspicious patterns and exquisite carvings. In addition, the screen wall can also set off the atmosphere, which can not only block the line of sight, but also facilitate access. Under the condition of not affecting people's walking, the shadow wall is better than the gate to play the role of shielding, blocking the line of sight and protecting privacy. In winter, the shadow wall can also block the strong wind and prevent it from blowing directly into the courtyard, which plays a role in buffering against the cold.
