No, no quite right - they are not in their graves any longer; they have arisen from death and are working in Beijing now.
This is at least what Hongtao Wu from China TEFL Network says. However, I wouldn't take his word for it; he is known to be a notorious liar!....LOL

WOW.. actually, we have had posters that went missing- in death they seem to multiply, and more that one poster claims to be a particular poster. One poster comes to mind-he was a nice bloke but really fiery and aggressive...now, he seems quite measured ,meek and mild- this is what multiplying in death can do for a body hahaha. Maybe Mao picks flowers and gives them to passing FT's.
