Where does the rocket burn coal in Degang Guo?

Degang Guo said that the rocket was burning coal in the North Exhibition Theater, and criticized the layman for guiding the expert. At that time, there was a joke in Degang Guo. For example, I told a rocket scientist that your rocket didn't work well and the fuel was not good. I think it is best to burn wood and wash coal, but it is not good to wash coal with water. If the scientist looks at me directly, he will lose his irony and guide the experts.

Mr Degang Guo's rocket burns coal.

There is a saying in Degang Guo, "For example, I told rocket experts that your rocket fuel is not good. I think burning coal as firewood is the best, and coal preparation is better, but washing coal with water is not good." Although it makes sense, the fact on the internet now is that a bunch of people say that rockets should burn coal seriously, and then more and more people follow suit, and then rocket experts have to come out and explain.

But many people still don't understand those professional explanations and insist that experts are bluffing. Now there are a bunch of people on the internet who don't even know where the door of that industry is, but they have a professional comment. Degang Guo once said a joke. I told rocket scientists that your rocket is not good and the fuel is not good. I think it is best to choose clean coal and water for coal washing.
