Legend has it that in ancient times, there was a Langzhong surnamed Liu who was skilled in medicine, but most of the patients he saw were able to cure the disease with medicine. He was regarded as a divine doctor in the local area and had a little reputation.

Liu Langzhong has a son named Liu Gong. He has studied medicine with his father since he was a child. Although he is not old, he has done his best. When his father is busy, he will also visit for treatment.

It is said that there is a rich man in Fujiazhuang not far away, known as Fu Million. He has a daughter to marry, and he doesn't know what strange disease he has recently. He has a poor appetite and is weak.

Pay millions to invite Liu Langzhong to see a doctor, but unfortunately, the old gentleman was not at home when he went out, so he invited Liu Gong back.

After Liu Gongzi arrived at Fu's house, he checked his pulse with Miss Fu through a bamboo curtain. After a while, Liu Gongzi said bluntly, "Congratulations, congratulations, it's a happy vein."

Fu Million almost fainted when he heard that. How could his girl be pregnant? It's just nonsense!

Fu Million thought that Liu Gong did not understand medical skills and insulted Fu family. Without saying a word, he called the servants of the family and beat the young master of the Liu family out with a stick.

Liu Gong went home with a limp and told Old Mr. Liu about it. After Old Mr. Liu heard it, he concluded that his son had not been diagnosed wrong, but had been humiliated and beaten. It was too much bullying.

The old man walked back and forth in the house without saying a word for a long time. Finally, he decided to see it in person to save his son's reputation.

Liu Langzhong instructed his son to guard the door at home and went to Fujiazhuang with his medicine cabinet.

When he arrived in Fujiazhuang, Liu Langzhong apologized to Fu Million when he entered the door. As soon as he took his seat, Mr. Liu said, "My son is young and ignorant, which makes Master Fu angry. It's all my fault for not being strict in teaching my son. Please bear with me."

Fu Million and his wife got a fever on their faces when they heard that, and they repeatedly told Mr. Liu that they were wrong.

Liu and Fu humbled each other, and Fu Million said, "Mr. Liu came at this time, presumably he hasn't had a meal yet. I'll treat you to dinner."

"No hurry, I'd better treat Ling Ai first." Mr. Liu said.

Fu Million and his wife followed Mr. Liu and came to Miss Fu's boudoir. Mr. Liu put on his glasses solemnly, first looked at his complexion, then called his pulse, and nodded secretly in his heart.

However, Mr. Liu did not point out anything, he just opened a pair of abortion pills and said, "I'll pay you to take this medicine, and it will be fine tonight."

Pay millions to receive the medicine list, while arranging to catch the medicine, while hosting a banquet to entertain Mr. Liu.

Mr. Liu did not leave after finishing his meal, sitting there drinking tea and chatting, waiting for Miss Fu to take the medicated soup. In the middle of the night, Miss Fu's stomach rumbled and the fetus fell out. Only then did the Fu family understand and hurriedly apologize to Mr. Liu: "It's all because the Fu family is not strict in teaching their children, and it's all because of the wind and evil."

Mr. Liu said he would not take a penny, but insisted on paying millions to his son to restore his reputation.

At this point, Fu Million had to agree to restore the reputation of the Liu Family Young Master. He prepared a heavy gift and made a gold plaque that said "Duke Liu's Divine Doctor" and gave it to Liu Gong. Soon, the Liu Family Young Master became famous all over the world.

After Mr. Liu's death, Liu Gong inherited his father's profession and practiced medicine everywhere, saving people urgently. Since Liu Gong had countless doctors and benefited the people, after his death, people honored him as "Master Liu Gong." When he offered incense at the Earth Temple, he also prayed to the Earth Lord to save the dead and wounded like Master Liu Gong and benefit the people.

Over time, Liu Gong gradually replaced the Earth Lord here and was worshipped for generations.
