Once upon a time there was a place called XQ. There lives a group of happy G. A. Y.
So one day, something called propositional composition was invented.
Ahem, I said seriously:
Probably one person posts a post every day, stipulates a time and topic, and then everyone writes a paragraph, usually with a word count of 300-3,000.
So this is the product of an illiterate person participating in proposition composition...
PS: The content summary is the proposition for each time...
