Li Yulong, the hospital's director of public welfare projects, known for her exuberant personality, led the team for the ninth time. She organized screenings for the children, recorded patient information, and occasionally handed portable oxygen tanks to doctors to help alleviate their altitude sickness.

Shigatse lies at an average altitude of 4,000 meters above sea level, and poses significant health challenges due to its high altitude and low oxygen levels, making it a hot spot for congenital heart disease.

On the evening of Dec 1, 2024, Huang Min, an ultrasound specialist from the medical team, reassured the last child and the family, saying, "The results are clear, everything is fine". This declaration marked the successful conclusion of congenital heart disease screening in the two counties.
