One of my inspiration points was a "red curtain incident" during the epidemic in Wuhan. At the period of epidemic isolation, a Wuhan resident filmed the curtains of his neighbor's house on the balcony for two months. He not only recorded the dancing appearance of the curtains, but also matched different background music according to different weather conditions. After the video was uploaded, it became popular all over the Internet. People thought it funny at first, but then they had a vague worry about whether the family was safe before they could close the window. And the messy red curtains have been fluttering in the wind and rain for more than two months. I feel that in such a sudden picture that breaks the normal life, the language seems to contain a sense of loneliness and desolation. Just like the people trapped in the city and the people trapped outside the city, because of the curtain, the heart is connected together. Red is a symbol of vitality, I also hope that through such a set of curtain devices to reflect the vitality of Wuhan people in the face of the epidemic.
