What are the folklore and anecdotes?

In ancient times, there was a scholar named Feng Yu. Feng Yu's family is very poor, and his parents are tenant farmers. After giving birth to Feng Yu, he didn't want Feng Yu to suffer like himself. He hoped that Feng Yu would get ahead and honor his ancestors, so he cut back on food and clothing and let Feng Yu abandon agriculture and join the literature, thus changing his fate. Feng Yu is also very diligent, plowing all day and reciting all night, just to be the top scholar one day, but he was unlucky in the exam, and his grades were abnormal, and he suffered repeated defeats and wars in Sun Shan. This is the last time Feng Yu went to Beijing to catch the exam. If he still misses, he has to accept his fate. Feng Yu traveled to Beijing from his hometown for about 20 days, and was about to arrive in Beijing, only to see a notice posted on the roadside tree in front of him, which read "This road is closed". It turned out that there was a rainstorm a few days ago, which washed down all the mud and stones on the roadside mountain and blocked the road. There are cliffs on both sides of the road, so it is impossible to go around. Feng Yu was very anxious after reading it, afraid of delaying the examination time. He asked an old man by the roadside if there was any other way to Beijing. The old man said that there is a barren hill more than ten miles to the south, and you can go straight through it for four or five days. Feng Yu thanked the old man and walked to the south. Soon, he came to the barren hills. Just as he was about to enter the mountain, he saw a Taoist lying under the tree by the roadside. The Taoist priest is dozing off with his back against the tree, his clothes are tattered, patched and covered in greasy clothes. Next to the Taoist priest, there is a half-eaten hard steamed bread and a bowl with a broken hose filled with half a bowl of water. Feng Yu saw the Taoist priest wearing clothes. When the Taoist priest heard the noise, he opened his eyes and saw Feng Yu put a few pennies beside his bowl. He was very unhappy and said to Feng Yu, "Hey, scholar, what are you doing?" Feng Yu saw the Taoist priest wake up and bowed to him, saying, "Leave this little money to the Taoist priest to buy some steamed bread."
