Can a chemistry teacher cook like Breaking Bad in reality?

Absolutely, because the principle of making drugs is very simple, but the materials needed and the control of each link need to be studied. In fact, it's ok to feel for yourself, but this is a felony area of breaking the law, and it's not that the teacher has no choice but to do so. Moreover, the reduction method used in this drama requires very high mechanical equipment, not to mention equipment like China and the United States. Of course, Lao Bai changed his method, either the steps were troublesome or the requirements for equipment were high. Anyway, it is basically impossible to make the drama pure.
