We visited Sun Yat-sen University, where Dr. Yucheng Li, an alumnus of our laboratory who completed his Ph.D. at our university in September 2024, is currently working. After the campus visit, Dr. Li kindly guided us to a local restaurant, where we enjoyed dinner together and lively conversations about research and daily life. Later, we joined a night cruise, admiring the beautifully illuminated cityscape and serene riverside views from the boat—it was a truly heartwarming and memorable evening.
