What is the difference between the abbot and the abbot of an ancient temple? Could it be the same person?

The abbot is equivalent to the general manager, and everything, big or small, must be involved. He is a man with more power in the temple. The abbot is a monk with high practice. He doesn't care about the trivial things in the temple, but leads the public to practice, meditate, lecture, preach and recite Buddha with himself. In some temples, the abbot and abbot may be the same person, but in some temples, there is only the abbot and no abbot. The abbot needs the approval of four people (or the Buddhist Association) and a ceremony called Ascension to Heaven. Can be regarded as the abbot of this temple.
