Does Shenzhen Post make money by express delivery?

Shenzhen Post doesn't make money by sending couriers, because the recruitment information released by Shenzhen Post Company shows that the average salary of couriers is 7,000 yuan, and the time is from 8 am to 7 pm. The average monthly rent for renting a house in Shenzhen is 1500 yuan, and with 50 yuan's daily necessities, there is about 4,000 yuan left in a month, so Shenzhen Post does not make money by sending express delivery.
