Things Zhang Zhehan did that led to his downfall:
1. Visiting the Yasukuni Shrine that worshiped class a war criminals.
2. Attending a friend’s wedding at the Nogi Shrine (dedicated to a Japanese general who led multiple Japanese invasion forces in China). Many of the guests present were members of the Japanese far right.
3. Posting a photo of a modded car full of Japan’s WWII era military symbolism (with the imperial army flag and a design based on Japanese WWII bombers that killed 20,000+ civilians during the Japanese bombardment of Chongqing).
4. Performing the Nazi salute in front of a war memorial and sharing photos on social media. Many of his fans later posted photos of themselves performing the Nazi salute at the same location.

Can’t blame anyone but himself even though I think it was a coordinated attack by his business rivals. I heard rumors he’s very arrogant and made a lot of enemies in show business.
