If traced back to the source, there should be two words in front of Amitabha called Nanwu, which means conversion in modern terms, and then it can be understood as a whole conversion to Buddhism, so two monks can also say hello to Amitabha Nanwu when they meet.
For example, when we watch some fantasy novels and TV series, we can often see the plot that a Taoist often meditates on Amitabha in the south when he appeases or kills a monster. To some extent, this represents the meaning of turning monsters.
On the other hand, Taoism also has a greeting when meeting, and the most commonly used one is boundless Buddha. The reason for this is that there are several particularly famous Buddha statues in Taoism, such as Infinite Buddha, Infinite Buddha and so on. In addition to greeting the boundless Buddha, it is also a common way to be merciful like a Taoist friend. For example, if the Taoist priest opposite you is surnamed Li, you can say that Taoist Li is merciful, and then you can say whatever you want in the future.
In addition, when we read The Romance of Gods, we all know that there is a famous saying in Shen that Daoyou please stay. This is also a way of greeting, but it is not commonly used. If nothing else, it is because this sentence is poisonous. The Taoist priests who were told by Shen to ask Taoist friends to stay are basically dead.
