Disregarding the weirdest propaganda meme I have literally ever seen.
Lei Feng died of very very non-natural causes, supposedly when he was struck by a telephone pole that had been hit by a truck.
It’s also worth noting that he was essentially just a caricature of the “perfect revolutionary” for the Chinese government, it’s very hard to establish any historicity to any of the things attributed to him.
It’s called second campism, and it’s been happening for a long time, it just used to make more sense when it could actually seem like there was two hegemonic camps during the cold war (still an oversimplistic view).
Now they just support any regime that’s anti-US/the original capitalist camp because they have no hegemonic camp of their own to support, just a broad smattering of authoritarian regimes with completely different ideologies.
