At 4:30 in the morning, the biological clock wakes up ten minutes earlier than the alarm clock. Long Plank gently opens the bedroom door, and the floor-to-ceiling windows in the living room reflect the hazy skylight outside the window - this is the staff living area of the "Yunjing Equestrian Club", with the green mountains at the back and the racecourse in front. The air is always filled with the faint smell of grass and horses.
