Jiang Ning hurried back to his courtyard, only to find Gucheng squatting on a tree like a lonely black owl, tilting his head.
"Hey, Gucheng, good morning!" Jiang Ning raised his hand and greeted him.
Gucheng looked down, as if he didn't expect Jiang Ning's way of greeting, hesitated for a moment, then responded, "Morning."
Jiang Ning chuckled and looked up at his beautiful, rosy and well-rested face, asking, "Didn't I tell you to sleep a little longer? There's no rush since we're already out."
Gucheng stayed silent for a moment, then said, "I see."
"How long do you usually sleep every day?"
"Three hours."
"Three hours..." Jiang Ning did a calculation in his heart, "That's six hours, which is too little for a child of your age. You should ensure you sleep at least four hours a day."
It seemed that Gucheng understood, and then maybe he didn't, only slowly responding, "I see."
