Ge Jun was in charge of writing papers last year. This year, the writer of the thesis is his deputy. Last year, Yao Tianxing was the second-in-command in math writing. He is an expert in modeling. Thanks to the exam, our teacher knew that it was him who produced the paper, and specially found some simulation questions for us to do.

The so-called modeling is a model problem to solve practical problems, such as this year's box.

It is obvious that he doesn't know what no one knows.
