About 200 meters from the main entrance of the cathedral is Gutenberg Square, the originator of movable-type printing in Europe. On the relief on the west side of the bronze statue, there are at least six Chinese characters. I was surprised to find out who this is. Gutenberg is the only one. Two foreign students who have lived here for 12 years have not noticed this detail. Looking at the previous comments, I know that many Chinese tourists have not paid attention to this relief. Today, Gutenberg Printer is still the world's first-class egg brusher.
