Why do you hang a three-foot-three red cloth on the door?

The method of hanging it on the door is as follows:

1. Pass a red rope through the red cloth and tie the red cloth above the door handle or door frame. You can hold the doorknob or doorframe with your arms, so that the red cloth can be hung vertically to express the meaning of celebration.

2. Fold the three-foot-three-long red cloth into three sections, and then tie the three sections of red cloth above the door handle or door frame with red rope or red ribbon. The middle section of the red cloth can be slightly elongated, and both sides are symmetrically tied above the door handle or door frame.
