What's the cloth on the hotel cup for?

What you want to ask is what is the cloth on the hotel quilt for? Decorate and keep clean.

Hotel quilts are generally pure white. Putting cloth strips on the quilt can make the color of the quilt not particularly monotonous and can play a decorative role.

Most people who stay in hotels are tourists or business travelers. After working or playing outside all day, when you want to have a rest when you return to the hotel, you can sit on the cloth strip on the quilt to prevent it from getting dirty.
