In 1984, an old lady who swept floors in Beijing announced that she would donate a huge sum of 2.4 billion to the country. What was going on? How could a seemingly ordinary and poor old sweeper in Beijing have so much money? What's the secret behind it?

The old lady’s name was Zhao Biyan. When she donated money, she claimed to be atonement for sinners. The criminal she mentioned was named Zhao Xinbo, and they were husband and wife. Objectively speaking, Zhao Xinbo is indeed a hateful guy. When Zhao Xinbo was young, he served in the Qing army and hung out for a while.

Later, because he wanted a better life, he found an opportunity to study at Peking University and learned some cultural knowledge. In 1911, the Revolution of 1911 swept across the country. Zhao Xinbo, who had a certain amount of knowledge, went to Beijing to develop.

During this period, Zhao Xinbo got to know some revolutionary workers because of the trend of the times. Later, he found an opportunity to join the National Government. Because of his status, he participated in some revolutionary movements.

In 1913, Zhao Xinbo participated in the second revolution with the people around him because of the changes in the times. It is a pity that this revolutionary movement of great significance to the times did not succeed because of the enemy's attack. After the failure, Zhao Xinbo fled to the Dalian area in a hurry because he was afraid of being killed by the enemy.

In order to deceive others and avoid subsequent arrests, he changed his name and infiltrated into an educational institution to serve as a Chinese teacher for the Japanese. This experience had a great impact on Zhao Xinbo's thinking. In 1915, Zhao Xinbo found the opportunity to study in Japan. He learned a lot at Meiji University in Japan and met many people in Japan.

After graduation, Zhao Xinbo was reluctant to leave Japan and found a way to work at the Army University in Japan. At that time, Zhao Xinbo's public identity was a Chinese lecturer, but his core mission was not to spread knowledge, but to explain China's intelligence information to Japanese military officers.

In 1925, Zhao Xinbo received a doctorate in law in Japan because of his relatively good performance. At that time, Chinese international students had not yet obtained such a degree, and Zhao Xinbo set a historical record.

Zhao Xinbo, who has been in Japan for many years, knows very well that the top leaders of the Japanese government have always been eyeing China and are always looking for opportunities to launch a war of aggression.

However, as a Chinese, Zhao Xinbo, instead of trying to stop Japan's invasion plan, worked in cahoots with some Japanese young officers and provided them with a lot of help. Later, under the arrangement of the Japanese, Zhao Xinbo worked beside the Northeast warlord Zhang Zuolin as a legal advisor.

Although he has returned to China, Zhao Xinbo's nature as a traitor has not changed. He is like a dog leg, trying every means to serve the Japanese. This despicable behavior was resented by many people.

But Zhao Xinbo didn't take it seriously. In his heart, he only had his own glory and wealth. In 1932, the puppet Manchukuo was announced to the outside world. Zhao Xinbo, a die-hard traitor, became the president of the Legislative Yuan with the support of the Japanese.

After gaining greater power and status, Zhao Xinbo tried every means to collect wealth and did many things to harm the people. In 1937, Zhao Xinbo was appointed as an adviser to the internal government. He was so proud that he wanted to do something with great ambition. However, he was accused by others before he was proud.

Because of suspicion of corruption, Zhao Xinbo was forced to resign from his post and took his family to live in Japan. After arriving in Japan, although Zhao Xinbo stayed away from politics, he still had some connections.

He joined forces with powerful figures in Japan to sell penicillin everywhere. This kind of thing was a very scarce medicine during the war. Zhao Xinbo quickly earned a lot of wealth by relying on this scarce material.

In 1938, Zhao Xinbo took his family back to China. After living in Beijing for a period of time, he became a high official again because of the invitation of Kenji Doihara.

A few months later, Doihara Kenji was transferred to the Puppet Manchukuo. As a consultant, Zhao Xinbo quickly lost his only power due to the loss of his backer. After that, he continued to carry out various tasks as a businessman and made a lot of money by relying on the turbulent situation.

In 1943, the Japanese army abandoned its base on Solomon Island due to successive defeats. The keen Zhao Xinbo immediately judged that Japan was about to be defeated. In order to protect his ill-gotten gains, Zhao Xinbo purchased a large amount of real estate in Tokyo.

Zhao Xinbo, who has a legal background, knows very well that these real estate properties must be managed by someone to truly protect them. After much thought, he finally found his friend Suzuki Yanosuke in Japan.

Zhao Xinbo knew that his identity was relatively sensitive, so he used his wife Zhao Biyan's name when signing the agreement. He thought he could rely on these means to leave some money for his wife and children so that they could live a worry-free life in the future. However, the shrewd Zhao Xinbo miscalculated in the end.

In 1945, the Anti-Japanese War was victorious, and Zhao Xinbo, a traitor, was quickly arrested. In 1951, Zhao Xinbo knew that he had committed a serious crime and died hastily in the detention center.

The real estate he bought in Tokyo that year has greatly appreciated in value due to changes in times. By the 1980s, the total value had even climbed to 3 billion.

Zhao Xinbo’s wife, Zhao Biyan, also tried to go to Japan to inherit this wealth, but was rejected. Suzuki Yanosuke, who had been entrusted with important tasks by Zhao Xinbo, directly claimed that the signature of "Zhao Biyan" on the power of attorney was fake, so he refused to hand over the property management rights.

What is even worse is that there are many scammers pretending to be "Zhao Biyan" in Southeast Asia. These people try their best to pretend to claim huge amounts of property, but they are rejected by Japan for various reasons.

Essentially speaking, the Japanese top management just wants to keep this wealth and is unwilling to return it to Zhao Biyan. After our country's leaders learned of this transnational dispute, they took the relevant situation very seriously and immediately contacted Zhao Biyan.

After verifying the relevant information, the state decided to recover the wealth. This is easy to say, but very difficult to do. From the beginning of the lawsuit to the final victory, it took the relevant departments more than 20 years to finally help Zhao Biyan and his family regain their original wealth.

Zhao Biyan is very grateful for the country's help. She knows very well that her husband Zhao Xinbo is a sinful person. In order to make up for the sins her husband has committed, she decided to take some money from her inheritance worth 3 billion. 80% will be donated to the country, hoping to provide some help for the country’s subsequent development.

When Zhao Biyan made this decision, her children in the family were very supportive. They knew very well that without the selfless help of the country, the money would not be recovered at all. It was indeed necessary to donate a sum of money to atone for the sins of their father Zhao Xinbo.
