The story begins in 1937, when the Lugou Bridge Incident had occurred, Beiping had fallen, a large number of students, teachers, intellectuals and patriots had been evacuated from Beiping, and even Tsinghua University had to move the whole school to a temporary campus in Changsha, and the whole country was shrouded in an atmosphere of turmoil and terror.

01 “乞丐”要见“校长”
One day in October of the same year, at the door of Tsinghua University (Changsha Temporary Campus), a ragged and unkempt beggar stood with a cane in one hand and a pickle jar in the other.
Seeing this, the security guard hurriedly drove him away.
He told the security guard that he was a teacher here and wanted to see Mei Yiqi, the then president of Tsinghua University.
When the security guard saw him like this, he naturally didn't believe that he was a teacher, let alone let a madman beggar enter Tsinghua University casually, let alone see the principal. Thinking that he was just faint from hunger and wanted to beg for food, he scolded the madman to leave as soon as possible.
The beggar didn't argue much, just stood like a statue, and then continued: I am really a teacher, please let me see the principal, I have something very important.
At this time, Principal Mei came out to see off the guests, and the beggar pounced on him and grabbed the principal's clothes, but because he had not eaten much for many days, he could only use all his strength, and shouted hoarsely, "Principal Mei!" and cried bitterly.
When the headmaster saw the beggar, he was stunned at first, then tears welled up in his eyes, and he quickly invited him into the office.
02 路行千里只为送“镭”
It turned out that he was a beggar, but Zhao Zhongyao, a teacher at the school who had been "missing" for three months!
The sauerkraut jar that he had been holding tightly in his arms was not filled with food, it was the only piece of 50mg finished "radium" in China at that time!

It is important to know that "radium" is an important raw material for nuclear weapons testing, and without this, it is impossible to carry out research related to nuclear weapons.
The "spark" of China's nuclear physics was thus protected by Zhao Zhongyao with his life.
Later, it was with this 50mg of radium that Zhao Zhongyao started China's first nuclear physics course, and he and his students Deng Jiaxian, Qian Sanqiang, Yang Zhenning and others officially started China's nuclear career.
Of the two bombs and one star father, one-third were his students
It is precisely because of their efforts that our country can successfully create nuclear weapons such as "Atom D" and "Hydrogen D", so that the world does not dare to underestimate us!

The above video is mainly about this story
So, why did Professor Zhao Zhongyao disguise himself as a beggar and walk more than 3,000 miles to transport radium?
It turned out that when the Japanese invaders occupied Beiping, Zhao Zhongyao happened to not be in Beiping, and Tsinghua University forgot about the 50mg of radium hidden in the laboratory due to its hasty move south (the bottle containing radium was very small and was hidden again, and ordinary people could not think of it at all).
This 50mg of radium was given to him by his teacher Rutherford when Zhao Zhongyao returned to China (you know, this 50mg of radium is not cheap, worth hundreds of thousands of dollars, and it is a scarce resource under control, and money may not be able to buy it)
His teacher, Rutherford, gave him a priceless treasure
He went through great pains to transport it back from England, and as an important element in the study of nuclear energy, radium could be said to be a priceless strategic resource in the world at that time.
If it falls into the hands of the Japanese invaders, the consequences will be unimaginable, and it may even wipe out the entire Chinese nation.
Zhao Zhongyao, who didn't have time to think deeply, risked his life and returned to Tsinghua Garden again, and after continuous searching, he finally found this precious radium in a corner.
This also made Zhao Zhongyao breathe a sigh of relief, but at this time, he faced a new problem.
That is, how to evade the search of the Japanese army and safely deliver Radium to his own people?
In order to be able to hide people's eyes and ears and avoid the Japanese criminals who are being investigated everywhere, Zhao Zhongyao decided to disguise himself as a beggar and walk all the way to Changsha.
Then he found a smelly garment, went to the canteen and took a jar of pickles, put a small glass bottle with "radium" in the pickles, and followed the refugees south.

From Beiping to Changsha, Hunan, in order to avoid the Japanese army and air raids, he tried his best to go out day and night, and walked for more than three months before he arrived.
In a blink of an eye, in October 1937, Zhao Zhongyao finally stood in front of the "Temporary Campus of Tsinghua University" in Changsha, Hunan, so the scene at the beginning of the article appeared.
And what more people don't know is that at this time, Zhao Zhongyao has been in close contact with the highly radioactive "radium" for a long time, and the skin and flesh on his chest have ulcerated on a large scale!
The history books are too small to fit their greatness!
Let us remember this "beggar", remember this nuclear physicist who has worked hard for the country all his life, China's "father of atomic energy", and the hero of "two bombs and one satellite" - Zhao Zhongyao!
