Electronic salute has the type of oil cannon, burning kerosene or gasoline and diesel, which undoubtedly pollutes the environment. Environmental protection by direct air excitation. There is no pollution to the air, no noise pollution to the environment, and speakers are not allowed to press, let alone gun barrels. During the trial, people came according to the standard of oil gun, unless you use a non-oil gun, you try your best to explain the non-oil gun. Didn't you have the equipment description when you registered? I used to register with the environmental protection department, but now all my documents are registered with the disposable industrial and commercial department. This thing is not easy to approve, just like the catering service license of a fast food restaurant in the city center. In short, you don't know until you try to register. I tell you, the state is very strict, and the government pays little attention to the funeral industry, fireworks, salutes, honor guards and so on. If you register an electronic technology company, or a company such as measurement and control instruments and robot equipment, the government will look forward to it. If you are a little famous, the government will pay special attention to it and have special support policies. You know, the cultural industry is the core of the nation, but cultural enterprises can't even get out of the province or even the city, let alone the top 500. Can the government notice the obvious limitations? I'm afraid it's a big blow to you It doesn't matter. You have to go by yourself anyway. There must be dreams. What if they come true?
