Why is Minnan Buddhism? But when people die, they are called Taoist priests?

As a custom in southern Fujian, the local religion in China is Taoism, so the deceased needs to invite a Taoist to practice. This has nothing to do with religious belief. If you want to invite lay disciples or Buddhist disciples who need Buddhist practice, you will only use Buddhism practice if the deceased has repented before his death. Some Buddhist monks have made contributions to the local area. On the day of death, monks or nuns will also come to the deceased's home to cross over.
