A tree hole can also be said to be a diary.
I write when I think of it, I write when I encounter interesting things, I also write on important days, in short, I write from time to time.
Three articles a day when I am happy, and one article every thirteen days when I am unhappy.
It's just the daily little things shared by ordinary people. If you like it, you can read it. If you don't like it, you can quit it.
What!
