When is the best time to wake up?

What time is best to get up? In fact, there is no accurate time. It needs to be determined according to people's habits. For example, go to bed at nine o'clock every night, sleep for eight hours, and get up at five or six o'clock. If you go to bed at ten o'clock in the evening, get up at seven o'clock in the morning. Generally, get up at no more than nine o'clock in the morning.
