There are watches and mobile phones. Although Fan Dazao bought his watch and mobile phone at extremely cheap prices and had used them for several years, he didn't need to check the time when he got up in the morning. He has been working in the hospital for many years and has long been accustomed to his own work and rest schedule. His brain is like the deep hemp rope marks left by the well in his hometown. I wake up early in the morning as usual every day, and the time I open my eyes is neither early nor late, always half past four. Fan had heard of the term biological clock a long time ago, but he just couldn't figure out the specific meaning of the term, and he didn't want to figure it out. He thought, Ha! What biological clock is not a biological clock? No clock is as accurate as the clock in my head. He didn't know that the reason he woke up on time every morning was because of his biological clock.
