My name is Bai Manchuan. I’m 18 years old and attend Xingchen University. I’m unmarried. I study in the library and return to my dorm after 8 p.m. every day. I don’t smoke, and I only drink in moderation. I go to bed at 11 p.m., making sure to get a full eight hours of sleep. Before bed, I drink a cup of warm milk and do twenty minutes of gentle exercises. Once I get into bed, I fall asleep right away. I sleep through the night and never let fatigue or stress carry over to the next day. Even the doctor says I’m perfectly normal.
