What does Nirvana mean?

In many inspirational articles, you can see the Chinese character "Nirvana Rebirth". Nirvana was originally a Buddhist term, which generally refers to inaction, freedom, immortality and so on. Nirvana rebirth is that Buddhism starts from the "origin theory" and reveals that human beings are empty and everything is empty.

"Nirvana Rebirth" means that the phoenix has experienced the ordeal of fire and the test of pain, gained rebirth, and reached sublimation in rebirth. People have given this persistent spirit of not being afraid of pain, never looking back, and constantly pursuing and perfecting themselves.

The legend of the phoenix's nirvana is that when the time comes, the phoenix gathers branches in self-immolation and is reborn in the fire. Phoenix is reborn after experiencing the test of fire and pain, which is the same as people's vision of expecting people to be reborn after suffering.
