For many people, working is only a means for survival. But Zhang Yu, a 37-year-old deliveryman in Wuhan, Hubei province, says it's also a chance for him to serve others, which has led him to be seen as something of a hero to those people and also helped him to become a delegate to the Provincial People's Congress in Hubei province.

After serving in the army for a few years, Zhang joined the SF Express Tangjiadun station in Wuhan in 2019. From then on, his routine has been the same: starting work every day at 6 am when the first rays of the sun break, picking up packages, sterilizing them, and distributing deliveries to his clients, before going home late in the evening.
