Is this regional, or perhaps urban vs rural? On my recent trip, I didn't see anyone using cash. Everyone used their phone. I bought coffee with cash at a Starbucks -- all the cash in their cash register was in a single roll held together with a rubber band. It was used so infrequently that they didn't use the trays or separate the bills.
Anyways, think about how much cash you use in the states? I think I last withdrew cash 6 months ago? And I haven’t used all of that yet, since there is maybe one Asian bakery I know of that charges for using a CC. The USA was already way ahead of the game on non-cash payments (via checks and then cards) and that has only accelerated since (not as fast as china’s move to mobile payments, but starting from a much higher level). So ues, even if they aren’t using cash in big Chinese cities, they aren’t using it in USA cities either.
Since as a foreigner I was never able to use wechat pay myself (the rules kept changing, but when I tried early on they couldn’t do anything without my Chinese ID number), I used to have to use UnionPay and cash for all of my financial transactions. So that was the end of 2016 when I left, more than a couple of years, so I’m a bit out of date. When I moved back the states, I became cashless again (having been cashless before moving to China in Europe and the USA).
Even the most faraway small villages residents use Alipay or WeChat, they don't even know what is a POS or ATM.

World Payments Report 2018 https://worldpaymentsreport.com/wp-content/uploads/sites/5/2...
China ranks the third of non-cash transactions organization after Eurozone and USA, and with its rate of growing, China will become the #1 in 2021, aka 3 years later.
Actually, in 2016, WeChat alone has already reached 500M transition/day[1].
As for cash propensity, it has nothing to do with non-cash transactions. Chinese ppl just love keeping lots of money in their bank accounts.
