After nine hours of rest in one night, he still slept until dawn. For an old man who is nearly sixty years old, this quality of sleep is almost unbelievable.

Yu Zhiming, who was somewhat envious and jealous, looked at Liu Lu with a questioning look.

Liu Lu replied somewhat sarcastically: "Doctor Yu, I now live in a house arranged by the school, with two bedrooms and one living room, and I share it with another young female teacher."

"In this situation, it is not convenient for my dad to live with me."

"I took advantage of some work conveniences and arranged for my dad to live in the graduate student dormitory."

She further explained: "Some graduate students rented houses outside or were interning outside, so the dormitories assigned to them were left empty."

"Now my dad lives alone in a dormitory, and I don't know exactly how he sleeps."

Yu Zhiming said softly and turned his attention to Liu Lu's father again.

"Teacher Liu, people who feel that their sleep quality is good may not necessarily be really good."

"Let's put it this way, at nearly sixty years old, you still sleep a full nine hours every day until dawn?"

Yu Zhiming said bluntly: "I am skeptical. I suggest doing a sleep quality monitoring."

Liu Lu replied: "I will take my dad to do it tonight..."
