Rainer's life was legendary.
He lived in China until he was eight years old, and then came to the United States.
As a Chinese person, in a discriminatory American educational environment, he excelled and dominated others, eventually winning the Fields Medal at the age of twenty-six.
Thereafter, he was recognized as one of the most brilliant mathematicians of the 21st century.
Although he grew up in the United States and changed his nationality, it did not mean that he had completely severed ties with China.
He was extremely upright and noble, full of sentiment, not only acknowledging his own blood, but also taking practical action.
He collaborated closely with many domestic universities, was happy to share his knowledge, and even helped train several outstanding international students from China, helping domestic universities to enhance their scientific research and teaching capabilities.
