"Ding dong!"
The rapid ringing of the doorbell is particularly harsh in the old residential building.
Chen Yu wiped the sweat from his forehead and climbed up to the fourth floor quickly.
He is a courier who shuttles through this reinforced concrete urban jungle, measuring the hardships of life with his legs and electric car.
Today's weather is extremely hot and muggy, and the air seems to be frozen, making people breathless.
He looked at the express delivery note in his hand. The recipient was Room 402.
Standing in front of the door, Chen Yu took a deep breath, adjusted his emotions, and put on a slightly tired but still enthusiastic smile on his face.
"Hello, your express delivery."
