MUC to HGK to BJS to MUC - Beijing Transit Visa

I would like to fly from Munich to Hong Kong, stay 4 days (visit Macau), then fly to BJS stay two days on a 72 hour transit visa and then fly back to Munich. I will be booking a multi city ticket from MUC to HGK/BJS to MUC. I will book the flight from HGK to BJS separately. Do you think I will have issue obtaining the 72hour transit visa?
