In the mountainous area of northern Fujian Province, there is a small town called Fengdao Town.

Eighteen years ago, Han Xu, the only man in the youngest generation of the Han family who moved from Jiangxi, met his wife Xie Shui here. At that time, the Han family did not have much savings, and after building a new house on a dilapidated temple, they did not even have the money to buy windows.

But Xie Shui lived up to expectations and became pregnant in just two months. In the cold winter after October, the cold wind was howling, Xie Shui was suffering from dystocia and hemorrhage due to his thin body, and when Xi Po shouted the news of the death of mother and son from the delivery room with a bitter face, Han Xu's sky collapsed in half.

At this moment, a man in his twenties passed by outside the door, and when he saw the situation of the Han family, he couldn't bear it, so he found Han Xu and told him that there was a gray butterfly on the mass grave in the west of Fengdao Town, as long as he grabbed it, unloaded his wings and made soup with the crow's eyes, and gave Xie Shui to drink, the child could be born smoothly, but Xie Shui was really powerless.

After hearing this, Han Xu immediately ran to the mass grave, and in less than an hour, Han Xu was covered in injuries, and he threw the gray butterfly in front of his relatives, and fainted.

Strange to say, Xie Shui and the child were silent early, but after Xi Po drank the soup for Xie Shui, the child soon crawled out of Xie Shui's belly.

Han Xu hugged the newborn child, but he was worried about the dead Xie Shui, so he named the child Han Shui.

Afterwards, in order to thank the man, the Han family learned that the man did not have a wife, so they married Han Xu's sister Han Li to the man, and the man hesitated again and again, and finally agreed, and became a son-in-law who was inverted and lived with the Han family.

Han Xu has fallen ill since he was looking for butterflies that night, and in less than three months, he was half-paralyzed and could only spend the whole day in a wheelchair. Fortunately, the brother-in-law who had the door upside down had a carving craft, and the statues he carved were all lifelike, and gradually became famous in the city.

And that Han Shui, who was frail and sickly when he was young, was asked by his uncle to stay in his room every year on the half-ghost festival in July and was not allowed to go out all night. Han Shui, who is still a child, doesn't know why his uncle did this, but he still does what his uncle says.

The story takes place when Han Shui turned eighteen.
