Do we qualify for a 72 hours transit permit?

Hello,
Me and my family are traveling from Sweden to New Zealand transiting China. We are flying from Amsterdam to Beijing arriving there 21:st of December 7.00 and flying directly 8.30 to Guangzhou where we are staying at a hotel until next day 22:nd of December when we are flying to Auckland.
Are we qualifying for a 72 hours transiting permit? We really need to know considering we are having 4 children with us.
Respectfully
Ioana
