Considering a visit to Shanghai in 2007 for Grand Prix

[Fredstar]

Im visiting Shanghai and Beijing next year around Sep-Oct, im from Shanghai so theres family there and also wanna go to the great wall and visit a few significant places in Beijing to absorb a bit more of my culture, during that time its possible for me to go to the Chinese Grand Prix, im a F1 fan but never been to any of the events so i really wanna do this next year, has anyone been to Shanghai for the race before? if so how was it, was it easy to get there and anything that I should know? looking at the map its pretty straight-forward logistically, my grandparents' place is near Hong-Qiao airport so its not as painful to get there compared to the actual drivers and their teams lol, i appreciate it if someone could share their experience...
