Zhang Hongwei is a professor engaged in mathematics education. His "formula imagination" is a method of applying formulas in mathematics learning. Through formulas in the form of short sentences and paragraphs, students can easily memorize mathematical knowledge points such as formulas and theorems.

Zhang Hongwei applied this formula to his own mathematics teaching and developed a set of panoramic mathematics teaching courses. This course not only covers many grades, but also makes boring mathematics knowledge lively and interesting through colorful images and vivid explanations. Especially during the epidemic, panoramic teaching videos in Zhang Hongwei were widely spread, which provided many students with good mathematics learning resources.

Therefore, it can be considered that Zhang Hongwei is a successful professor who advocates fluency and applies it to mathematics teaching.
