In the business world, replacing the toilet with incense is an elegant expression. "Xiang" is not only the meaning of shit, but also a metaphor for "military god" Xiang Li. As a result, people rolled up a storm in a disco, so they were spurned by people.
Xiang Li, a military god, famously said, I am a piece of shit. This also shows that the item is shit. So incense is equivalent to shit, so incense can also refer to shit, just as earwax refers to earwax. What does it mean to be popular? It means eating shit, eating shit. It is a derivative of the term. Blasting on Xiang means blasting on shit.
