Have To Go

In the afternoon of that same day, at the mathematics research lab of the Chinese Academy of Sciences, Professor Xiang Huanan was sitting quietly.

With his reading glasses on, he was reading [Annual Mathematics]. He had a pen in his hand, and every now and then, he would write on the paper.

To learn was to grow, especially when it came to research in mathematics.

New research results were born ever month. He did not want to fall behind, so he would read every new edition of Annual Mathematics.

Suddenly, an unexpected guest visited his office.

The guest smiled and shouted, "Old man, what are you doing?"

When Professor Xiang Huanan raised his head, he saw Professor Wang Yuping walking into his office. He then took off his reading glasses and said with a smile, "Hey."

He looked at the student next to his desk and said, "Xiao Li, give Professor Wang some tea."

"Okay!"
