How to change the bulb of this lamp? The lampshade will not fall off if it is twisted for a long time.

Generally speaking, for light bulbs, in fact, I think you said that this lampshade of your light bulb can't be unscrewed for a long time. Because personally, the reason why you can't take down this lampshade is because you are too tight and compact. If your lampshade is too compact, this problem will occur. So personally, it's really not very good, so I think if you really change the light bulb, it's best to be a professional maintenance person. Because I think professional things should be done by professional people.
