Medical missions in China are like when a group of doctors and other medical professionals go on a trip to help sick people in China.
China is a really big country with a lot of people who need help, and sometimes it can be hard for everyone who needs medical care to get it. That's where medical missions come in - these doctors and nurses and other helpers go to different parts of China and bring their medical know-how and equipment with them to help people who might not have access to those things otherwise.
During these missions, the medical team will often set up clinics where people can come and talk to the doctors, get checkups, and get treatment for whatever health problems they might have. The doctors might also hold classes to teach people about different health topics, like how to stay healthy and avoid getting sick in the first place.
Overall, medical missions to China are all about helping people who might not have access to medical care. They're like superheroes who use their medical skills to make the world a better place!
