I'm Lin Fu, a physics student from Central South University. It's my honour to participate in this summer school and have a chance to reflect on the fulfilling journey with my fellow classmates. Honestly, this is the very first time in my life when I have come together with numerous brilliant physics students from all around the world to exchange knowledge and explore the magic of physics with prominent physicists.

Before I got here, most of my knowledge about physics came from books. They were just cold formulas and complicated math calculations, and I've never truly grasped the essence of what physics is all about.. However, the professors at TDLI revealed a fascinating truth to me: there exists a community of scientists engaged in research that previously, I had only witnessed in science fiction movies.For example, Black Hole, Supernova, gravity and so on. And that's incredibly fascinating. Furthermore, the faculty here welcomes us with exceptional warmth and approachability. They address our queries with exceptional patience and attentiveness. Their unwavering commitment to academic rigor and their fervent passion for communication are invaluable qualities that no textbook can impart. Having experienced all of this, I've gained a clearer vision of my preferred research path and a deeper understanding of the essential qualities required to excel as a physicist.

Moreover, the diverse and vibrant extracurricular activities provided the perfect complement to the enriching experience of this summer school. The delightful welcome dinner, the splendid Shanghai planetarium, the peaceful and beautiful campus of Shanghai Jiao Tong University, and the spirited, and energetic basketball match have all etched enduring memories in my heart. These wonderful memories also remind me that no matter how long and difficult the road ahead is, never forget to make yourself happy.

I wholeheartedly express my gratitude to every student here. Meeting you guys is a precious gift of fate that I cherish deeply. I would like to thank Ms. Zhao Wunaji, Ms. Shi Hui, Ms. Jin Xiaoqian and all the supporting members at the backstage for making this summer school perfect.I am deeply grateful to Shanghai Jiao Tong University and TDLI for providing this exceptional platform, which has facilitated our invaluable personal and academic growth.. In the future, I hope to become a member of TDLI, to continue the story originated in this summer and to realize my life aspirations!

I conclude my remarks here, and with heartfelt appreciation, I would like to express my gratitude to everyone once again!
