To put it bluntly, chemical consulting is chemical design, including planning design and chemical design itself. If you go to a design institute, you'd better get a qualification certificate. It used to be difficult, but now there are more and more, and there is not much gold in becoming a professional certificate.
If you want to get a doctorate and like to engage in scientific research, you must stick to it. After all, good chemical enterprises, especially large chemical enterprises, multinational companies and doctors are all a threshold, and those qualification certificates are useless.
