Destination details within China

I'm an Australian citizen and I'm currently completing my Chinese tourist visa. I'm due to fly to Beijing on 24 or 28 August. We are due to return to Australia on 12 September, 2023.
From Beijing, my Chinese girlfriend and I will be visiting, Harbin, Yunnan and Guizhou provinces. However, at this stage I don't have any addresses & dates where we will be staying in Yunnan and Guizhou provinces as it all depends how long we stay in Beijing and Harbin. Can you advise what I should put on my Visa application as to Section 6.1 J . Thank you.
