Those stories that used to be

Once, the newspaper posted on the soil embryo wall was 1985 to catch up with the Premier League, and now, no one dares to move the soil too old;

Once, the earth supported up to 7.5 billion people, and today, the earth not only spans 7.5 billion but also vigorously advocates eugenics;

Once, there must be a great plague after the great tribulation, and now, in the year of the great catastrophe, the year without famine and the plague is still healthy;

All that was once has been, and all that is now will eventually be what has been. Live well in the past, do a good job in the present, and strive to do a good job in the coming present, and you will be worthy of the past and the present.
