Written at the doctoral graduation ceremony.

20 18. 10.28 is the annual doctoral graduation ceremony of the hong kong polytechnic university, presided over by Carrie Lam Cheng Yuet-ngor, the chief executive of hong kong. The ceremony was solemn and unforgettable. However, my family and I spent a long time in Shanghai without much regret. After the doctor graduated, all this faded. It is not the moment when the doctoral diploma is issued, nor the day when the ceremony is to be held, but the early morning when the review opinions come back. At that moment, I felt that my doctoral career had not been abandoned, and my doctoral research could continue. Although the tutor is guided by Buddhism, he has always given encouragement and support, because he has my belief and my continuation in his sight.

During my PhD, I am very grateful to my family for their deep understanding and support. I am also very grateful to my roommates for their help and companionship. We talked together, watched movies and listened to plays together, discussed scientific research together, visited Victoria Harbour together, watched fireworks together and climbed mountains together. It's hard to get together often in the future. I wish everyone well. It was the most in-depth study time in life, and it would be a pity if anyone inadvertently neglected it.

The early work in the industry made me happy and uneasy, for fear that I would forget my original heart when I was running around. Now, I have a place in the quiet campus, and I am fighting for the world.
