Mathematics, as a universal subject, is not limited by national boundaries, and its principles and theorems are applicable everywhere. But mathematicians, as human beings, also have their own sense of belonging to the country and the nation, and they will be proud of their country and nation, and make contributions to their development and progress through their own work.

Mathematicians often engage in research and teaching in their own countries to promote the development of mathematics in their own countries and cultivate more mathematical talents. I will also participate in academic exchanges and cooperation at home and abroad, share my research results with mathematicians from other countries and promote the development of mathematics.
