In the long river of ancient times, the name of Peng Zu is like a bright star, shining with mysterious and charming light. As a legendary long-lived person, his secret of longevity has always been talked about by later generations.

Peng Zu lives in a peaceful and beautiful place, where mountains and waters depend on each other and green trees are shady. His residence is a simple hut surrounded by lush flowers and trees. Peng Zu is wearing a simple robe, with white hair but in high spirits. There is a kind of peace and wisdom in his eyes.

One day, a young man heard of Peng Zu's reputation for longevity and came from afar to ask him for the method of health preservation. The young man came to Peng Zu's hut full of expectation. After respectfully saluting, he asked, "Senior Peng Zu, I have heard that you are a long-lived person. I have come to ask for the method of health preservation. I hope you will not hesitate to give me your advice."

Peng Zu looked at the young man with a smile and said slowly, "What I cultivate lies in harmony. In terms of diet, don't be greedy for heavy-flavored food; in terms of daily routine, work at sunrise and rest at sunset; in terms of state of mind, don't be angry or resentful, but be optimistic and open-minded."

After hearing this, the young man seemed to understand but not quite understand, so he asked Peng Zu to explain further. Peng Zu nodded and began to elaborate on his way of health preservation.

"Harmonious diet is the fundamental of health preservation. Food is the source of life, so we must choose it carefully. Heavy-flavored food, although it can satisfy the appetite for a while, will burden the body. We should eat more light food, such as vegetables, fruits, and whole grains. These foods are rich in nutrition and easy to digest, and can nourish the body. Moreover, we should be moderate in eating and not overeat to avoid damaging the spleen and stomach."

The young man thought for a while and asked, "Then how can we be moderate in eating?"

Peng Zu replied with a smile, "Learn to listen to the voice of the body. When you feel hungry, eat an appropriate amount, but don't eat too much. When you feel full, stop eating immediately and don't be greedy anymore. At the same time, pay attention to the regularity of diet, eat regularly and in proper amounts, and don't disrupt the diet rhythm at will."

Then, Peng Zu talked about daily routine. "Harmonious daily routine is to conform to the rhythm of nature. Working at sunrise allows the body to bathe in the sunlight and absorb the yang energy of nature, which helps to boost the spirit. Resting at sunset allows the body to get sufficient rest in the quiet night and restore physical strength. We must ensure sufficient sleep and not stay up late to avoid consuming essence."

The young man asked again, "But in today's busy society, many people cannot work at sunrise and rest at sunset. What should we do?"

Peng Zu patiently explained, "Although we cannot completely follow the natural rhythm, we should also try to maintain a regular schedule. In busy days, we should also take time to rest and let the body relax. We can take a nap at noon or go to bed early at night to make up for lack of sleep."

Finally, Peng Zu talked about state of mind. "Harmonious state of mind is the key to health preservation. Not being angry or resentful, being optimistic and open-minded can maintain inner peace. In life, it is inevitable to encounter various setbacks and difficulties, but we cannot resent and be angry because of this. We should learn to face everything with a peaceful attitude, maintain an optimistic attitude, and believe that difficulties will always pass."

After hearing this, the young man was deeply inspired. He gratefully said to Peng Zu, "Senior Peng Zu, your way of health preservation has really benefited me a lot. I will definitely remember your teachings and try my best to practice the way of health preservation."

After the young man left, he spread Peng Zu's way of health preservation to more people. After hearing this, everyone followed suit, and sure enough, they were all in good health.

As time went by, Peng Zu's secret of longevity was widely spread among the people. People began to pay attention to light and moderate diet, maintain regular daily routine, and cultivate an optimistic and open-minded state of mind. After many people practiced Peng Zu's way of health preservation, their physical conditions were significantly improved and their lifespan was gradually extended.

However, Peng Zu's secret of longevity is not only a health preservation method, but also an attitude towards life. It reminds people to cherish life, care for their own bodies, conform to the laws of nature, and face everything in life with a peaceful attitude.

In this fast-paced modern society, people are often busy with work and life and ignore their own health. Peng Zu's secret of longevity provides us with a valuable inspiration, allowing us to re-examine our lifestyle and return to a simple, natural and healthy state of life.

Let us take Peng Zu as an example, be harmonious in diet, daily routine and state of mind, and pursue a long and healthy life. In this beautiful world, feel the miracle of life with a peaceful attitude and meet future challenges with a healthy body.
