Can I visit Beijing on a day trip if transiting at PVG airport in Shanghai?

My flight schedule is this:
HKG --> PVG on July 29th (72 hour transit permit in Shanghai)
PVG --> MNL on August 1st (layover)
MNL --> HNL on August 2nd (final destination USA)

Do I qualify for the 72 hour transit permit? and am I able to do a day trip to Beijing during the 72 hour transit period? I'd like to book a day trip package through a travel agency in Shanghai.
