As far as I recall, everything else that is negative, except 1989, was taught in secondary school history class.

This is not correct. I grew up in China (Beijing to be more specific) and it is definitely not taught in school. All history I’ve learn casts China as having done everything right.

Were you taught using 人教版 or 北师大版 history textbook? I'm pretty sure 四人帮 and 大跃进 were inside 北师大版 and called a mistake. Well at least for my year. Maybe they changed it, or you didn't pay attention in class.
