The glass of the lampshade on the head is broken.

This is natural and should not be associated with good or bad luck. Otherwise, there will be concerns about asking for trouble. Plastic products usually age and crack naturally. How does it contain good luck or bad luck? Right? It's just that a broken lampshade that falls will scare people. The past is the past. If you clean it up, you will be fine. Just replace it with a glass one to prevent it from cracking and scaring people.
