What is the phrase on thunder and lightning?

Persuade people to study medicine, and the sky thunders.

Persuading people to learn Dharma is one thousand yuan; Persuade people to take exams, thunder and thunder; It is better to be a dog than to persuade people to break up.

From the internet, it is used to ridicule the difficulty of studying medicine and the bitter study career.

First of all:

The study period is too long, and it may take seven or eight years to graduate from medical school. After all, the patient gave his life to you, and you must take responsibility. But for students, 78 years of prime time has been wasted, and many people may not last that long.

Second:

At present, doctors are also a high-risk profession. I think if everyone knows something about doctors, they will pay attention to them. It is also dangerous to work overtime without saying anything.

But if you are interested in a doctorate, you can study it, but if you just want to find a good job or something, choose your favorite major.
