Is There a Difference Between 1989 and 1989?

In Tiananmen Square in 1989, there were two main constituent groups: students and workers. In China today, the class composition of those people are different. The experience that they've had in the Chinese system is very different. And then also, I think some of them are more interestingly is like it's not the same working class that showed up in 1989 because that class doesn't really exist anymore.
