"Through the experiments at Haohang Lab, I have gained a completely new understanding of physics. I used to think physics was abstract, but now through hands-on experiments, I truly understand the principles behind those formulas."

"Jim's experimental designs are very interesting, and each experiment gives us new discoveries. Especially the light interference experiment - when I saw those beautiful interference fringes, I was truly amazed."

"At Haohang Lab, I not only learned physics knowledge, but more importantly, I learned how to think about problems and how to design experiments. These abilities have been very helpful for my studies."

"The atmosphere in the lab is great, everyone is very active and helps each other. Here, I found the joy of learning and also made like-minded friends."

"Jim's physics notes are very detailed and helpful for my review. He also shares study insights and problem-solving techniques, which helped me avoid many detours."

"Through participating in Haohang Lab activities, I developed a strong interest in science. Now I have decided to study physics in the future and continue exploring the mysteries of science."
