As for why it is called Gong, I found that none of the above people explained it. Let me explain it. It was at Hitler's suggestion that ferdinand porsche designed the classic model of the Beetle, which is also the origin of Volkswagen. Volks in German has the same meaning as Folks in English, which means "human". Wagen corresponds to the English word Wagon, which originally meant carriage, but in the 1930s, the horse was "retired", so the carriage can also be called a carriage. So the word Volkswagen was translated as "people's car" and later became "Volkswagen".
In fact, the most standard translation should be Volkswagen, but as everyone knows that this is an automobile manufacturer, it has been simplified to Volkswagen over time.
