Why are there few books that have been turned up and down except almanac?

Calendars, calendars and calendars are not for reading. Every page of it is a symbol of a certain day (the calendar has 1 page, and it has been drawn for 1 month, which doesn't help). In order to record the passage of time, it must be expressed by violent "tearing" or "turning pages". Yesterday cannot be forgotten. People should look forward and bid farewell to the past. Tearing off those old days one by one is "living". After tearing a book, it's Spring Festival, so it's time to hang a new book. There are also books that turn pages, which seem to be unpopular and waste paper. You can abandon it at the end of the day, and you don't have to look at what you should avoid and what the solar terms are. Tearing it off or lifting it to the back is the best choice. Besides, an almanac like a book is easy to find on the desk, but it is not suitable for recording dates. Once it is messed up and blown away by the wind, you may forget today's date. After all, when the Gregorian calendar was invented in the past, there was no TV, radio or Internet to report the sun. Nowadays, the mobile phone calendar is powerful, and it can be queried by year, month and day through real-time weather forecast, which is unimaginable for people who tore paper before. But tearing off that piece of paper every morning is more ceremonial than glancing at the phone. It feels like you have a symbolic entity in the past day, even though it is just a piece of paper. There are still relatives and friends who insist on using old calendars and tear one every day. Ten years ago, he had an electronic watch that could show the date at the press of a button. It took him two days to tear up the calendar. Now I don't have my mobile phone in my waist, and I still insist on tearing it. Buying an old almanac with poor printing quality and as thin as cicada's wings is not suitable for breaking ground today. This situation seems to have not changed much for decades. No matter how you commemorate it, there will be no same day after that day. Tearing off a piece of paper is like telling yourself that there is water under the bridge. I am not a good old man. I think everything today is better than in the past. Still, I occasionally feel nostalgic. The song sings: the faint old days have slipped away like this, and the morning after waking up is my sadness.
