Well spotted Barry I see we both do the same drugs!
I shall en devour to explain....je ne regret rien is an anagram.
Re-arranged it comes out as Re-entering Jeer. A chapter title from the Silk Road.
Getting clearer? Jeer as you probably know Barry, is a village in China in -as you so cleverly noted-the Schuan province (responsible for the discovery of willow pattern plates,bound feet,chop sticks and other famous piano ditties ) and in its heyday (1302AD) it became host to that most famed explorer Marco VW Polo his father and uncle Mafeo (founder of the famous Venetian Mafeoso an institution that still bears his name today!).
This man (Marco) brought back from his touring many artifacts. One of the lesser known was the symbol you refer to etched on a piece of petrified Yak dung. Somehow (and this part of the tale is shrouded in mystery) it made its way from the top shelf of Marco`s glass display cabinet to the Louvre in France where it stays to this day.
It was only during the hostilities of the second world war,when Bunito Muscleini researching his book Da Da Vinchy Code discovered the true meaning of the rune. And that was? I am sure you are in front of me here Barry-the surrender of Frances sovereignty to the Fascists. In return the fascists agreed to leave all the crap French engineers in place at the Renault/Peugeot/Citroen works ,so that they may continue to design crap cars after the cessation of hostilities. A legacy still apparent today.
Hope this clarifies things,and once again jolly well done.
Sparkin up!
