Excuse me, what good job does Debon logistics courier have?

I just resigned the day before yesterday. I'm not a courier. I'm a fucking porter. What is the concept of sending 2 to 60 kilograms upstairs? Unload two cars every day, 6.8 meters and 9.6 meters, and arrive at 9 o'clock after work? You don't need to work in Debon if you want to do express delivery. Note that Debon has made a fortune in logistics, and express delivery is still young.
