The "hanging garden" needs neither sunlight nor watering, but only the warmth of electric lights. Although I don't take special care of it at all, it is still beautiful. I love it so much, when I moved to a new house, I was still worried about how to take it with me, and finally I decided to take it apart and take it with me. Now, with such a great piece of history, the secret lies within the abstract celestial body in the new house.
