I think the cultural revolution screwed it all up when it comes to remembering things like this. It's well over but the mentality with older generation is still there. I wonder if there is a demand with this generation to take a personal interests since educational interest doesn't seem to be happening.

Without a doubt if it could make money someone would be profiting from it, China loves capitalism. It is kind of nice the family didn't sell out their heritage for profit and that the sites are private, it shows someone must be doing something behind those closed doors, maintaining in the least.

I've noticed in China if anything has cash value they put a fence around it instantly and charge a fee to look at it. lol
