One day, Plato asked his teacher Socrates what love was. Socrates told him to go to the wheat field once or go back. Pick the biggest and best ears of wheat on the road, but only once. Plato found it easy and went out with confidence. But he still didn't go back for a long time. Finally, he appeared in front of the teacher in frustration, telling the reason why he returned empty-handed: "I finally saw a seemingly good plant, but I don't know if it is the best." Because I can only choose once, I have to give up and see if there is a better one. When I found that I had reached the end, I found that there were no ears of wheat in my hand. " At this time, Socrates told him: "That is love."

Plato asked his teacher Socrates one day what marriage was. Socrates told him to go to the fir forest once or go back. On the way, take the best and most suitable tree materials for Christmas trees, but only once. Plato learned the last lesson and went out with confidence. After a long time, he dragged a fir tree, which looked tall and green, but a little sparse. Socrates asked him, "Is this the best wood?" Plato replied to the teacher: "Because it can only be taken once, I finally saw a seemingly good tree and found that time and physical strength were running out, whether it was the best or not, so I took it back." At this time, Socrates told him: "That is marriage."

Another day, Plato asked his teacher Socrates what an extramarital affair was. Socrates still told him that once he went to the Woods, he could walk back and forth and pick the most beautiful flowers on the road. Plato went out safely again. Two hours later, he came back with a bright but slightly faded flower. Socrates asked him, "Is this the best flower?" Plato replied to the teacher, "I searched for two hours and found that it was the most beautiful flower in the garden, but it gradually withered on my way home after I picked it." At this time, Socrates told him: "It was an affair."

Another day, Plato asked Socrates what life was. Socrates still told him that once he went to the Woods, he could walk back and forth and pick the most beautiful flowers on the road. Plato learned from the past and went out with confidence. After three days and nights, he didn't come back. Socrates had to go into the Woods to find him, and finally found that Plato had camped in the Woods. Socrates asked him, "Did you find the most beautiful flower?" Plato pointed to a flower beside him and said, "This is the most beautiful flower." Socrates asked, "Why don't you take it out?" Plato answered the teacher, "If I take it off, it will wither at once. Even if I don't pick it, it will wither sooner or later So I lived next to it when it was still in full bloom. When it fades, I will find the next flower. This is already the second most beautiful flower I have found. " At this time, Socrates told him: "You already know the true meaning of life."
