According to the 2020 China Health Statistics Yearbook released by the National Health Commission, there were about 155,000 pediatricians in China in 2019, while there were 249 million children under 14. In other words, there is only one pediatrician for every 1,610 children, while, on average, there are nearly 30 adult specialized doctors for every 1,000 people, suggesting there is a severe gap in the current number of pediatricians and the demand for their services.

When he was a medical student working as an intern, he was surprised by the lack of medical resources in the neurosurgery department for children, which resulted in many not receiving proper treatment.
