What is the last one in the jargon of Chinese opera?

Ancient books are made of bamboo slips, so the regular script in the past was just a long scroll with a scroll under it, just like a framed scroll of Chinese painting. Because the last scene of the long scroll is close to the wooden shaft, it is called the big shaft. The scene in front of the big axis, that is, the penultimate one, is called the finale, the middle one is called the central axis, and the front one is called the initial axis.

In the past, a drama performance called a program "Big Axis", the last program called "Big Axis" and the penultimate program called "Grand Finale", so from a purely academic point of view, it is actually wrong to call the last program "Grand Finale" now.
