There were Celestial Masters who got lost and wandered off from Dragon Tiger Mountain.
There were the unlucky ones who trapped themselves while playing around.
There were old demons who evaded capture from the Righteous Path, found places to infiltrate, and then just fell asleep, forgot to emerge from the mountains.
There were those who despised the worldly prosperity, believed everyone on Earth was an idiot except themselves, and refused to communicate with anyone unless they reached the pinnacle of cultivation–the reclusive paranoid old ascenders.
