On the 100th anniversary of the founding of the People's Republic of China, Chen Jianguo traveled back 100 years ago to the day when the whole world celebrated the founding of the People's Republic of China. With the expectations of the motherland and the people, he brought a large amount of science and technology back to the beginning of the founding of the People's Republic of China, helping the motherland defeat powerful enemies, allowing China to rise rapidly, and allowing the Chinese nation to stand on top of the world again.
