After working for 15 months in the China-Sierra Leone Friendship Hospital, the 21st medical assistance team to Sierra Leone from Hunan province returned to Changsha on Sunday.
The 20-member team, including 19 medical workers from departments of internal medicine, surgery, pediatrics, anesthesiology and others, arrived at the hospital in the nation's capital city of Freetown in June 2019, providing medical aid to local residents.
