In 2018, Yingjie found about the Downfall Parodies by watching videos of Payday 2. He bumped into a random Hitler Parody called Hitler plays Payday 2 by Awesome Face!. He was curious as he knew that Hitler did not actually play any video games. After watching the parody, he thought that the subtitles were 100% accurate, so he continues to watch more parodies by random Untergangers.
When he bumped into a parody, it said that "The subtitles are 99% inaccurate. This is a PARODY.", he realized that Hitler did not really play any of his favorite games. Inspired by this he made his first parody called Hitler rants about BW3 Episode 1.
