In his search for the origins of the Aryan race, Reichsführer-SS Heinrich Himmler conducted several expeditions into the Tibetan state during the late 1930s. What is lesser known, however, was that there were also some expeditions carried out to the Republic of China with the same goal, approved by Chiang Kai-Shek himself. Most of the documents are still locked to this day, but Himmler's findings were astounding and brought him shame - he discovered that Aryan roots came not from Tibet, but from China, and that the true present-day Aryans are the Han Chinese. Furthermore, he discovered that most Germanic traditions are actually offshoots of Han Chinese ones.
This angered the Reichsführer-SS, who kept these secret.
I share you this knowledge, but you already know this. Why do you cower in the face of Han Chinese supremacy? You will not be exterminated.
