What is the function of a dash in a sentence

What are the functions of dashes?
Dashes are used to indicate the explanatory statements in a text, or to indicate semantic conversion, progression, interruption, extension, etc
The usage of dash is different from bracket: the explanation in dash is a part of the text, and the explanation in bracket is not the text, but a comment
Its main functions are as follows
1. Indicates a comment
(1) Stepping into the golden gate, through the wide hall and cloakroom, you will arrive at the central hall, the hub of the city hall
[hint] the difference between bracket annotation and dash is as follows
"When Mrs. Yang saw this incident, she thought she was very good at it, so she took the dog gas to kill (this is our chicken raising equipment. There is a fence on the wooden plate, which contains food. The chicken can stick into its neck to peck, but the dog can't. She can only watch the gas die) and ran away like a bird."
2. A change of meaning or topic
(2) The memory of collecting firewood on the mountain is still happy - though it was a very hard work in childhood
(3) "What a delicious dish - have you heard the wind?" Zhao Qiye said standing behind Qijin
