Liu Heida was busy with the company's affairs.

Jin Yan was lying alone on the old wooden bed in the old house without a mattress, looking at the somewhat moldy roof, thinking about the old childhood things of playing with his parents, and constantly pondering.

He carefully observed the copper lock, the appearance looks no different from the ordinary copper lock on the market, the brass lock body, the stainless steel lock ring, 20 yuan Donghua coin on the market can be seen everywhere.

He entered it with a strange ability, and there was nothing unusual.

First of all, one thing is for sure, parents will never use a useless thing to tease Uncle Da to play with themselves, there must be a mystery in this copper lock.

If their parents are really not alive, they entrust such a thing to Uncle Da and let him hand it over to him when he is strong, which also has a meaning, that is, a relic.

"I wish to have one heart, and the white head will not be separated. Do not change the softness. ”

The handwriting on the plastic card is mottled and blurred due to the age of time, although it was originally written with a charcoal pen.

He remembered that this poem came from a folk poem in ancient times in Donghua, called "Baitou Yin", which has been circulated for nearly 2,000 years and is well-known. When he was a child, when he was about three or four years old and learning to learn language, his parents took him to recite this poem from time to time.

This poem seems to be included in a book of "500 Children's Songs".

That book was the main reading book that my parents took me to learn to read aloud when I was a child.

He turned and walked to the study. There are three large bookshelves in the study, and there are all kinds of books on the shelves. I haven't been back for a few years, the books on the shelves are very clean, and there is no dust, it seems that Uncle Da comes to clean from time to time.

There are about six or seven hundred books on the shelves, most of which are about poetry and ancient books, and a small part are various strategies for pregnancy and parenting, as well as children's books and picture books that Jin Yan read when he was a child. The books are very old, and some of them have been torn apart by him when he was a child, and they are unrecognizable, but they are still kept on the shelves.

I heard Uncle Da say that in fact, there were originally two bookshelves, which were full of ancient martial arts, ancient arts, notes, etc., which were all about the ancient martial arts practiced by the ancient martial artists of Xuanhu, but later after the parents disappeared, an official person came to raid the house and copied all the relevant books and various items and photos of the parents.

He rummaged through it, and finally found the tattered children's book "500 Nursery Rhymes" from the shelf.

It is indeed in tatters, and it is still scribbled by my childhood self with all kinds of colored pens, and there are broken pages and broken pages everywhere. Some of the faces on the portraits of the ancients were painted by themselves into all kinds of messy monster faces.

Touching the book, he felt as if he had instantly returned to his childhood.

The blurred and distant faces of their parents came back to mind.

His father is handsome and handsome, and his mother is gentle and virtuous......

Returning to reality from the contemplation of the past, he gradually turned the book to the page of "Baitou Yin". The full text of this ancient poem goes like this:

Wen Jun has two intentions, so he decided to break up.

Today's wine fight, Mingdan ditch head.

On the ditch, the ditch water flows from east to west.

Sad and miserable, there is no need to cry when you get married.

I wish to have one heart, and the white head will not be separated.

The bamboo pole is curling, and the fish tail is so curling!

Men are heavy-minded, why use money knives!

The general meaning of the poem is the cherishing of love between men and women, the yearning for love, and the hope for sincerity, believing that love should be as pure as the snow on the mountain and as bright as the moon among the clouds, which cannot be compared with any treasure.

When my parents were back, it was really romantic. He thought to himself.

Suddenly, his eyes fell on the word "Yugou". These two words were sketched by children's watercolor pens, but he keenly noticed that several of them were not drawn by him as a child. And it was not drawn by other children, its handwriting was completely different from the casual nature of children.

He hurried to find other books. There are some places on it with the handwriting of the parents. With his current eyesight, he soon discovered that the strokes on the nursery rhyme were his father's handwriting.

Parents would never scribble on his own books.

He looked at it slowly, then took out his mobile phone and searched for this ancient poem in the search engine, paying special attention to the word "Yugou".

The place where this ancient poem was produced was in Lingong City, Xichuan Province in ancient times, and Yugou was a local irrigation canal, which was named Yugou because the monarch of the ancient Xichuan Kingdom had visited Lingong City.

It turned out to be a place name......

Xichuan Province is located in the southwest of Donghua Province, about 2,000 kilometers away from Dongming Province. Lingong City is an ancient city with a history of more than 3,000 years.

What does it mean to cross out this place name in particular?
