Osaka - Beijing - Hong Kong (with a transfer in the middle)

Hi, I have a flight from Osaka, Japan to Beijing (with transfer in Qingdao) and then two days later to Hong Kong. I realize this should be no problem based on the ticketing, but because my flight is not direct from Osaka to Beijing (i.e. makes a stop in Qingdao) will that not allow me to do the 72 hour transit visa? The booking I made was a single trip, not two separate trips, but it just happens that I must transfer in Qingdao. I'm a bit confused on this, so would appreciate some help. Thanks!
