At that time, the European powers were still on the rise economically. Some short-sighted westerners are arrogant and look down on students from poor and backward China. Zheng is inevitably discriminated against. Unexpectedly, after the end of the first academic year, Zheng from China ranked first in the mathematics exam of Paris University! China students won the first place in the exam, which is unprecedented in this famous European school, so that a local newspaper actually ran a "sensational" headline: "French mathematics is dangerous". Zheng won honor for his country. With the help of our embassy in France, he won a scholarship from China. In a small hotel on the fifth floor of the fifth campus of the University of Paris, Zheng stayed up all night and studied hard. His favorite places to go are libraries and laboratories.

Paris University is the hometown of some world-famous scholars and scientists. Zheng received strict basic knowledge training and was influenced by famous teachers here. One of his mentors has a great influence on his life's career. She is Madame Curie, a French physicist and chemist from Poland. She appreciates this studious student from an ancient oriental civilization and often gives special guidance. Zheng went to the institute of radium science of the university immediately after he got his bachelor's degree? Madame Curie became the first graduate student in China to study radiochemistry with Madame Curie.

Madame Curie is a great woman who has won two Nobel Prizes and loves peace. She always tirelessly rewards and teaches others. She not only encouraged Zheng to fight for the backward motherland in spirit, but also influenced Zheng with her own scientific opinions and helped him to do experiments and write papers. Only in 193 1 year and 65438+February, Zheng published three papers in the Journal of the French National Academy of Sciences. 193365438+In February, the Defense Committee of the Faculty of Science of Paris University, with Madame Curie as the chairman, unanimously passed Zheng's doctoral thesis, and Zheng obtained a doctorate in French national physical chemistry.
