This emperor, who lived for five generations, lived for 93 years and ate only one meal a day. A habit lasted for 40 years, that is, Zhou Guifei of the Northern Song Dynasty. The only meal that Zhou eats every day is actually just a very ordinary vegetarian meal. She keeps the habit of reading Buddhist books day and night. Even if she falls asleep, once she wakes up, she will go to school again immediately. Reading Buddhist books (cultivating indifferent mentality) is the secret of her longevity.

It is said that Zhou's study time is over 40 years. During Zhou's 40-odd years of schooling, she never fell asleep on her own initiative. Why did you have the habit of fasting and chanting Buddha that week? This is because Zhou was born in a civilian family. Although she grew up in the palace, she was later favored by the emperor and gave birth to a princess, but she knew she could not compete with others. Moreover, because she grew up in the palace, she was indifferent to those jealousness and jealousy things in the palace, so she didn't want to fight with others in her heart.

It is precisely because she has no idea of competing with others that she has developed the habit of worshipping Buddha day and night. It can be said that it is Zhou's idea that everything is dull, Zhou's reasonable and regular eating habits (one meal a day), and her pious heart that has kept her alive for so many years.

As the saying goes, once a person is in a good state of mind, everything will go smoothly and he will feel relaxed when he is alive. So, if such people don't live long, who will live long?
