Why is there only 18 floor left in the sales office? /kloc-is there any taboo on the 0/8 floor?

Countdown to eighteen levels of hell. I haven't heard of any problems on the 18 floor upstairs. 18 to go. This is the lucky floor. Now some people are mentally ill, and some people prefer 7 to 8, saying 7 up and down 8 times. In fact, 7 is the number of the underworld. Don't all the dead burn 7? So, don't be superstitious about numbers.
