Width of bright window glass = (sliding up and down size -7cm)/2

Height of bright window glass = center pillar+1.2cm.

Three doors up and down (with four hooks? ) = (up and down length-10.5cm)/3

Three fans are growing up and down (with four companies? ) = (up and down length-12.6cm)/3

Four fans without middle seal = (sliding length up and down /2-8cm)/2

Inner yarn height = hook length-2cm.

Outer yarn height = hook length+0.5cm.

The middle seal size is 3.2cm.
