My landlord preferred to be paid through Alipay. I had to pay in cash because Alipay wouldn't let me make payments that large. (Because my Alipay account was backed by a foreign credit card as opposed to a Chinese bank account, I assume. If you're curious, the rent was about US$700 / month, so the payment would have been about US$2100.)

I don't see that landownership is really relevant. Mostly it's done on the basis of notional 70-year leases from the government. Since the government dates to 1949, the first round of those recently expired. There was a lot of curiosity beforehand as to what would happen, but it doesn't seem to have made enough of a splash that anyone commented about it (where I could see) afterwards. So I don't know how it turned out.

I understand that rural peasants may sometimes own their land outright. In this case, I was renting one apartment in a building with 5-6 floors and I think 4 apartments per floor.
