Miscellaneous

I love soccer. See how our team lifted the championship trophy 🏆 (a video with audio) in my high school, 2020, and achieved the runner-up 🥈 in the freshman cup of Peking University, 2022!

I am a big fan of Real Madrid. See my friends and I when we watched Madrid win the 2024 Champions League final. Many of them are fans of Barcelona! 😈
