2020 is the beginning of the disaster in human history. The pandemic of Covid-19 has lasted for two years. People have began to wear masks and the border has been blocked. During the level 3 epidemic alert period in Taiwan, the possibility of going out has been reduced. One day I was stuck at home thinking of foreign landscapes, the idea came up with this series of plans: Imagine Windowsills. Using the synthesis of photos to replace the outside world with the place you want to go. It is no longer having flats, high-rise buildings, concrete walls, or the next door neighbor's house that cannot see the light out from your window. In the imaginary window sill, you can go to places that you want to go.
