As heartwarming as Jiang's work, Witness – You Are the One I Care About Most, a photo installation shining spotlight on doctors' empathy for and bond with their patients, pulled at the heartstrings of many audiences.

Featuring a number of portraits of medical workers who hold up their phones to show a photo taken with their patients, the installation is a work by Li Ge, a veteran photojournalist who spent 66 days in Wuhan, the city hit hardest by COVID-19 in China, documenting the city's battle against the epidemic.

Li and his team took more than 40,000 such portraits of the medical workers sent to Wuhan to aid the fight against the virus. During the shooting, Li was deeply touched by how much those doctors and nurses cared about their patients.
