Is there a simplified word before simplification?

In fact, most of the simplified characters we use now existed before the implementation of the 1955 simplified character scheme, which is only a further arrangement and standardization of folk writing for thousands of years.

These simplified characters can be seen in many ancient books and ancient inscriptions.

Many of the characters printed on the Ming dynasty wall tiles in Nanjing are also simplified characters that are still in use today?

The word "Gai" on this rubbing is the same simplified word as today.
