Well, I can't generalize for every Chinese person, but if you want to get a sense of how "close" the Cultural Revolution feels to many here, think of some famous event that was happening in your own country in the 1960s and 70s. For Americans, that would probably be the Vietnam War. Feels like recent, yet ancient, history. 

The youth of today, those born in the 80s and after, have no personal connection to this stuff really. Their parents, however, were there, and remember. My Chinese friends have told me that their parents either never bring it up, or talk about it as a tragic, scary time. But there are also a few elderly folks I've met that remember that time with fond nostalgia, mostly because there was a sense of common purpose and struggle which is lacking in the consumerist culture of today, the same way soldiers sometimes remember war time with a certain nostalgia, because life was simplified down to a single mission, and when you're cold and tired and hungry, when there is a clear enemy, your troubles are less existential, and there's a certain measure of romance and comfort in that.

When I first got to China in 2002, the subject was still taboo, and there was a sense that people were still nervous about criticizing it too much. The Party line at the time was, "Mao was 70% good and 30% bad" - that was said again and again in newspapers and on TV, that 30% being the concession to the nasty things that happened during the Cultural Revolution. But as time has moved on, and China has opened up, there is now no sense of nervousness about talking about it. I've read many public speeches and essays from prominent politicians stating that the Cultural Revolution set China back more than any other period in history. At the same time, Mao is still China's founding father - China's George Washington. His head is on the bank notes. So he's not universally hated by any means, as he did do some good things as well. But I would say that among educated urbanites, there is a common recognition that the Cultural Revolution was a bad idea. 

In terms of how "Cultural Revolution-y" modern China feels on a day-to-day basis? Not at all, really. Cultural Revolution kitch is still sold at tourists sites and in antique shops, but on a day-to-day basis, it's in the past.

Lei Feng is a kind of special case... he's still well-known because he's such a perfect person to point to as a people's hero, and his name is still synonymous with selfless, good-hearted patriotism, so "be like Lei Feng" is kind of an easy thing to say to children. But this is kind of like the George Washington and the Cherry Tree story, you know?
