This umbrella inside and outside the window breaks the limitation that the traditional umbrella surface cannot see the outside world by properly "opening the window". It also uses the element of "window" to combine the relationship between the inside and outside the window, and visually guides the clean umbrella surface outside the umbrella with the small window, thus arousing people's curiosity to find out. Finally, when they see the rich and colorful life track of the ancient people in the window, their mood is suddenly clear, to add interest to life.

The visual pattern is taken from the popular classic works of "Spring Dawn Picture of Han Palace" and "Shanghe Picture on Qingming Festival", which is derived from this "umbrella in the window".
