The story of "Dog Bites Lu Dongbin".

Before Lu Dongbin became an immortal, he was originally a scholar. Among his friends was a fellow villager named Gou Ji. Gou Ji's parents died, and his family was poor, but he was loyal, an honest gentleman, and a diligent student. Lu Dongbin appreciated him very much, worshipped him as the Jinlan brother, and invited him to live in his home, hoping that he could study hard and have a bright future in the future.

One day, a guest surnamed Lin came to Lu Dongbin's house, and when he saw that Gou Ji was a talented person and studied hard, he said to Lu Dongbin that he wanted to marry his sister to Gou Ji. Lu Dongbin was afraid that Gou Ji would miss the bright future by coveting the joy of the bed, so he hurriedly pushed it off. Unexpectedly, Gou Ji himself heard that Miss Lin was beautiful and insisted on agreeing to this family business. Lu Dongbin thought for a long time and agreed. He said to Ke Ji: "Since the virtuous brother has made up his mind, I will not stop it, but after getting married, I will sleep with the bride for three nights." Gou Ji was taken aback when he heard this. Under the fence, how can you not bow your head? Besides, all the expenses of the wedding have to rely on the Lu family, who makes themselves destitute? After thinking about it, I gritted my teeth and agreed.

On the day of Gou Ji's marriage, Lu Dongbin was overjoyed, running before and after running everything. But Gou Ji had no face to see anyone, so he simply hid to the side. In the evening, the guests were sent away, and Lu Dongbin entered the cave room. I saw the bride with a red veil on her head and sitting on the bed. Lu Dongbin didn't lift the red hijab, nor did he speak, just sat under the lamp and buried his head in reading. Miss Lin waited until midnight, but her husband still didn't go to bed, so she had to sleep with his own clothes. When I woke up in the morning, my husband was long gone. It's been like this for three nights in a row, but it's hard for Miss Lin, and when she turns around, she finally survives three days, and just enters the cave room, she sees that the lady is crying sadly, and she bows her head and cries and says: "Why didn't Lang Jun go to bed and sleep together for three nights, just read to the lamp, came in the dark, and left in the morning?" This question made Gou Ji stunned. The bride raised her head and looked at it, and was even more surprised: Why did her husband change someone? After a long time, the couple suddenly realized. Gou Ji stomped his feet and looked up to the sky and laughed: "It turns out that my brother is afraid that I am greedy for joy and forget to study, so I use this method to motivate me!" Miss Lin was also happy in her heart and full of respect for Lu Dongbin. Both husband and wife said: Brother Lu will repay this kindness in the future.

A few years later, Gou Ji was named on the gold list and became a big official. The couple and Lu Dongbin's family said goodbye in tears, went to work, and eight years have passed. In the summer of this year, the Lu family accidentally caught fire, and a huge part of the family wealth was turned into ashes. Lu Dongbin and his wife had to live in a thatched hut made of broken bricks and tiles, needless to say, life was difficult enough. Lu Dongbin had no choice but to go out and find Gou Ji for help. After a lot of hardships along the way, I finally found Gou Jifu. Gou Ji was very sympathetic to Lu Dongbin's house and received him warmly, but he didn't mention helping. Lu Dongbin lived for a few months, and he didn't get any money. Lu Dongbin looked up to the sky and sighed: "Human affection is as thin as paper, and it changes as soon as you have a broad face, and it is all over the world!" In a fit of anger, say goodbye without saying goodbye.

When he returned to his hometown, Lu Dongbin saw that his dilapidated thatched house had been replaced by a new tiled house, and he was very surprised: he was far away, and his son and wife were weak, how could he build a large number of buildings? When he approached the door, he was even more shocked that the three souls walked twice: there were white papers pasted on both sides of the door. Someone died in the family? He hurriedly entered the house and saw a coffin parked in the house, and his wife was wearing linen and filial piety, and was crying. Lu Dongbin was stunned for a long time: Which Dai filial piety is she? Softly called: "Lady." The lady looked back, frightened, and trembled and cried out, "You, are you a human or a ghost?" Lu Dongbin was even more surprised: "How did the lady say this? I'm back fine, how is it a ghost?" The lady looked at it for a long time before she dared to believe that it was really Lu Dongbin who came back, and said, "Oops! It really scared the hell out of me! It can't be a dream, can it?" It turned out that not long after Lu Dongbin left home, a group of people came to help him build a house, and he left after building the house. At noon the day before yesterday, another group of people brought a coffin, saying that Lu Dongbin was sick and died at Gou Qi's house. When his wife heard this, the sky fell and she cried to death. I'm crying today, I don't want Lu Dongbin to come back.

Lu Dongbin knew in his heart: it was all a trick played by Gou Ji. He picked up a sharp axe and slashed the coffin. With a "click", the coffin split, and it was full of gold and silver treasures, as well as a letter. Lu Dongbin unfolded the letter and read: "Gou Ji is not a negative man, and he will send the gold and silver family to build a house. You let my wife keep the empty room, and I will make your wife cry and break her bowels. Lu Dongbin woke up like a dream, and smiled bitterly: "Virtuous brother, you gang can help me so hard!"

Since then, the two families of Lu Gou have become more affectionate. This is what the saying often says, "Gou Lu Dongbin, I don't know the hearts of good people", because "Gou Qi" and "dog bites" have the same sound, and it has become "Dog bites Lu Dongbin, I don't know good people's hearts".
