What sort of place is this?

The weekend went by without an incident.

Monday morning.

His father was packing Chenchen's bag according to her class schedule.

His mother had just finished preparing breakfast. Seeing that it was about time, she opened her son's bedroom door to wake him up for breakfast.

"Son, it's time for breakfast!" his mother shouted loudly.

However, the moment she stepped into the room, she saw that he was already awake.

Zhang Ye was scribbling on some documents as he answered her without even raising his head to look at her. "OK, Mom."

His mother wondered, "Heh, why are you suddenly feeling so perked up? You've been like that for the entire weekend already. I don't see you sleeping at night, and by the next morning, you're already up before I even wake up. Has the sun started to rise from the west? What have you been writing for the past few days? Didn't you get frozen by the station? What are you still working so hard on?"
