The sentence you asked about comes from "Mending the Wall" by Frost, a famous modern American poet.

As for the sentence you said, "A good fence can only have good neighbors." This sentence in the poem is similar to our country's traditional governance thought of "deciding divisions and stopping disputes, only then can long-term stability be achieved." This means that the scope of rights and obligations must be clearly demarcated for matters related to one's own interests or value orientation, and no controversial matters or issues should be left behind.

"Fence" means "to settle disputes and end disputes", while "good fence" means to make appropriate and clear definitions of rights and obligations and other issues involving mutual interests, and also to have Full and keen foresight. "Good neighbor" (or "good neighbor" as you gave it) means that only by establishing "good" "fences" can conflicts of interest, disputes, or potential crises between each other be well coordinated and calmed down. Toward healthy development.

In addition, I attached the original poem as follows:

"Mending the Wall"

There is something, it probably doesn't like the wall,

It caused the frozen ground at the foot of the wall to swell,

In broad daylight, it caused stones to fall from the top of the wall:

It caused cracks in the wall, and the two of them stood side by side. Get by.

The gentry made another mess when they were hunting:

They would lift the stone off every stone,

I always followed them to mend,

but they would drive the rabbits out of hiding,

to please the barking dogs. No one saw or heard how the crack in the wall I mentioned

came about.

But when I repaired the wall in the spring, I saw it there.

I notified my neighbor who lives on the other side of the mountain;

One day we had a date to inspect the property boundary,

There was another time between our two families. Put the wall back up.

When we walked, there was a wall between us.

When we left, there was a stack of pei in between.

The stones that fall on each side are taken care of by each one.

Some are long and some are almost round like balls.

It takes a little magic to put them in place:

"Stay there, wait until we turn around and then fall down!"

We move rocks. The fingers are all roughened.

Ah! This is just another outdoor game,

one person stands on one side. Besides, it's not much use:

Where the wall is, we don't need a wall at all:

His side is full of pine trees, my side is an apple orchard.

My apple tree will never walk past

Eat the pine cones under his tree, I told him.

He just said: "Good fences make good neighbors."

Spring is playing tricks on my heart, and I am wondering

Can I put a thought into it? Inject into his mind:

"Why do good fences make good neighbors? Does it mean

people with cows? But we don’t have cows here.

What is being enclosed and what is being enclosed,

And who I might offend,

There's something about it, it doesn't like the wall,

It wants to knock it down. "I can tell him it's a "ghost."

But strictly speaking, they are not ghosts. I think it's up to him to decide. I saw him there

carrying a stone, clutching the top of the stone with both hands,

like an armed savage from the Paleolithic age.

I think he is groping in the dark,

This darkness comes not only from the deep woods and the shade of the trees.

He refused to explore the maxim passed down to him by his father.

He thought of this maxim and liked it so much.

So he said it again, "A good fence Create good neighbors.”

Because my major is law, the above mainly talks about my views from the perspective of legal thought. If you are very interested, there are many related poetry collections in the bookstore, and the library resources are even richer. It is recommended that you combine it with books on legal thought to think about it.

The above are some of my own opinions. I hope it will be helpful to your studies. Please correct me for any omissions.

Answer added :

I saw the supplement to your question and I know that you are going to discuss the issue of group communication with the teacher through this proverb. First of all, let me explain that this proverb is indeed a Western proverb, and the source has been stated.

If you think about it from the perspective of communication between people, I personally think you can add to your point of view. The strong fence that separates people shows that on the one hand there is less communication between various groups, but on the other hand It is precisely because of the existence of a solid fence that unnecessary and dispute-prone communication between each other is reduced, and "benign" communication between people is introduced. This kind of communication cannot be quantified by communication frequency/quantity. It depends on how much, but what is worthy of recognition is that this "complete separation" as you said has ensured the interests of individuals, or each group, and the order of life.

A little insight, looking forward to further discussion.
