Weihan was an extraordinary human being. He was a loving son, a devoted husband, a responsible father, and a loyal friend. His kindness, generosity, optimism, and fun-loving spirit touched the lives of everyone around him. He was also a brilliant economist. His intelligence and passion for economics were inspiring, and his enthusiasm for learning was infectious. As a friend, Weihan was simply the best. He was loyal, supportive, and always there when you needed him. He had an infectious personality and a great sense of humor, and he could always be counted on to make his friends laugh and to lift their spirits when they were feeling down. He was a great listener and always had a kind word or a thoughtful piece of advice to offer. Our friendship began during our undergraduate studies at SUFE, and we continued to stay in touch throughout our time at LSE, in London, and beyond. Our conversations were always engaging, thought-provoking and entertaining, covering topics ranging from economics and global politics to family and personal matters as well as dark humor jokes. Weihan had a way of making everyone feel comfortable and valued, and his sense of humor and quick wit were always a source of laughter and joy. In fact, I still remember the days and nights spent with Weihan, and I miss him dearly. He was always so generous, sharing with me the latest notes, papers, and books he had come across and inviting me to attend his supervisor's lectures. He even introduced me to his friends, always going out of his way to make me feel included. Whenever he discovered a new delicious restaurant in London, he would immediately think of me, eager to share the experience with me and invite me to dine with him next time. And whenever I felt down or lost, he was always there by my side, providing comfort and encouragement. Even in the last few months before his passing, he remained so positive and optimistic that we had made plans to meet up for meals in Shanghai or Nanjing once he recovered. I still remember that summer night in 2019 after we submitted our dissertations, standing on the terrace of Weihan's apartment in Stratford, drinking and smoking, dreaming of the future ahead of us and reveling in the joy and beauty of our friendship. The memories are so vivid, but it's hard to believe that Weihan is gone. Weihan's passing has left a deep void in our lives, but his memory will live on forever. He was a wonderful human being and a beautiful soul, and he touched the lives of so many people with his kindness, intelligence, and generosity. Weihan was an extraordinary friend and person, and I will always cherish the memories we shared together. Rest in peace, my dear friend Weihan. You will be deeply missed, but never forgotten.
