My name is Lu Qiao, and my dad is a physicist.

Through my dad, I set up a Sina Weibo and gained millions of followers.

It's better to talk about Dad, it's better to talk about the project that Dad is working on at this time.

The purpose of these fans and me is also for this project, which is the black hole of the earth.

As the name suggests, the Black Hole on Earth was three years ago, one day in 2043, when the tourist attraction of the North Great Wall in Beijing suddenly collapsed and a fist-sized hole appeared.

Witnesses at the time said that the ground suddenly collapsed without warning, and it was not caused by human trampling, or that it suddenly shattered and a circular hole the size of a fist appeared, and the hole was very round.

The news was broadcast on a local station in Beijing at the time, and not many people cared about it at first.

The staff of the Great Wall of the North also handled it in a very simple way, taking cement to fill in the holes in the ground.

But the following week, the cement covering the hole fell again.

Tourists reported the matter again, and then it began to receive more attention.

This black, circular hole was cemented by the staff of the Northern Great Wall for the first three months.

And a warning sign was inserted next to it, but the filling again and again caused the hole to reappear.

It wasn't until the last filling, three months later, that a larger cover was covered directly over the hole.

The matter was truly over, but only at the Great Wall of the North.

There have been many pictures of the holes in the Great Wall of the North on the Internet, and there have been many comments saying that the holes are getting bigger and bigger. So the filled cement will fall into it after the holes get bigger, and over time black holes like this appear all over the net.

The places here are not all over the country, but all over the world.

Some people have made rumors and some people have confirmed that many of the holes on the Internet are fake.

There are even many videos of chance holes that are made by artificial special effects, but it is not excluded that the hole photos in many places are real.

And each country's approach to holes is different, ranging from complete secrecy to open handling.

Most conservative countries cover it up, and a small number of it is covered with glass for tourists to visit.

It was the first month that the hole appeared, and the president of the United States met with the Chinese premier. After the two state leaders visited the Great Wall with their wives. At the suggestion of the President of the United States, the Chinese Premier once again opened the hole in the North Great Wall that had been covered by the cover.

At this time, the hole was no longer just the size of a fist, but in the blink of an eye, it was already a head wide.

The bold president of the United States reached into it, touched the wall, and then took it out to indicate that the hole under the Statue of Liberty in his country was the same, and that the interior was extremely smooth.

Later, the hole in the Northern Great Wall was also covered with glass, chained around and protected by management 24 hours a day.

It is open for eight hours a day for visitors, and the state has personally sent a team of leading experts in physics and geology to conduct research.

My father's name is Lu Youwei, and he is the top physics professor in Nanjing.

I was also asked by Beijing, and I happened to be admitted to Peking University in the same year.

My dad agreed and went to Beijing with me.

That's why my dad lives in Beijing, and I study at Peking University.

At first, I begged my father to take me to the place where he studied in order to visit the Great Wall for free, and then I became interested in holes.
