Going to get the 72 hour transit visa but my onward flight has another stop over in china

Hello

I have a big problem here :(
Tomorrow I am flying to Beijing will be applying for the 72 hour free transit.

2 days later I am flying from Beijing to Sydney. I thought all was good and well until I realised that my flight to Sydney has a stop over in Nanjing Airport. From what I've read, the visa conditions say you cannot stop off at another airport in China during your onward flight.

I'm very worried as I have very little money (I'm on my way home) and I don't want to be rejected from my flight which I already paid a lot for and is non refundable.

Has anyone had any experience with this? I'm wondering if there is any sort of leniency?

Thank you
