You may not know that when the light bulb was invented, no one paid attention to these inventions at all, because people would rather have no light than use anything else. Zhao Ming is not used to using the light bulb, because its light-emitting time is too short and unstable, so people don't like him to make the price of the light bulb drop rapidly and make the light bulb shine for a long time through Edison's continuous efforts. At this time, the light bulb entered thousands of households.
It is no exaggeration to say that the light bulb is one of the greatest inventions from the last century to this century, because it makes our life, our city and everyone realize how bright the neon is at night and what life is like during the day, but we don't know that the light bulb appeared in that year, but it didn't attract much attention.
