Dear Professor Hofert, this is a letter waiting to be sent for a long time, but before it was sent, you had already left us. After graduation, I coincidentally became a teacher in university, and every time I recall the time spent with you, I can find new inspiration, especially the work completed under your guidance: Open Prison: Knitvana. I didn't have the chance to tell you that this work was been selected to participate in the 2020 Futurelab International Education Exhibition in Shanghai West Bund, and will also participate in the 40th Anniversary of the Faculty of Architecture and City Planning Exhibition of Kunming University of Science and Technology in December 2023. Although it is not a perfect work, I hope that the concepts in it can inspire more people. It was not until I became a teacher that I realized what a wonderful constructivist teaching I had experienced, and with your support and encouragement, I began to experiment with my wild and poetic design concepts. I will always remember the comment you gave me at the end of the studio: "Now you finally become a human." Yes, since then, I finally understand the meaning of tolerance, and I will follow your example to become a better man, a better teacher and architect.

May all be well with you in heaven and rest in peace.
Your Chinese student: Shi Yanghongyi
