Xu Guangqi (1562-1633) was a famous scientist and mathematician in the late Ming dynasty. He is one of the outstanding representatives of ancient mathematics in China and an important contributor to surveying and mapping technology, astronomy and physics. Xu Guangqi is mainly engaged in mathematical research, and has written such important works as Shu Shu Jiu Zhang and Tian Yuan Shu.

But there is no direct connection between Xujiahui and Xu Guangqi. Xujiahui was named after Xu, not Xu Guangqi. Xujiahui gradually formed a prosperous business district in modern development and became one of the important business centers in Shanghai. There are many shopping malls, office buildings, restaurants and cultural facilities in this area, attracting a large number of business activities and people.

Xu Guangqi was an outstanding scientist and mathematician in the late Ming Dynasty, and his character evaluation mainly focused on his academic achievements and contributions. Xu Guangqi has great attainments in the field of mathematics, and he has made important contributions to many branches of mathematics such as algebra, geometry and number theory.

His book Shu Shu Jiu Zhang is one of the classics of ancient mathematics in China. It put forward many unique mathematical methods and problem-solving skills, which had a far-reaching impact on later mathematical research.

As a surveyor, Xu Guangqi has also made important contributions to surveying and mapping. His book Tian Yuan Shu systematically summarized and recorded the surveying and mapping technology, which was hailed as a milestone of ancient surveying and mapping in China and played a positive role in promoting the development of surveying and mapping in later generations.

In addition, Xu Guangqi has made important research achievements in the fields of astronomy and physics. He made in-depth observation and research on the laws of celestial motion and physical phenomena, and made remarkable achievements in astronomical observation and celestial mechanics.
