I wouldn't. They'll just handle it differently than we would in the US.

https://tradingeconomics.com/china/unemployment-rate - It's around 5% per this (and some other sources I found, just linking the one). The population being around 1.4 billion people, that means around 70 million unemployed. That is already mass unemployment despite having a low rate of unemployment across their national population. And that's before getting to their youth unemployment rate which is around 15%, which sets them up poorly for the future.

"Mass unemployment" can't be based on raw numbers instead of rate, as otherwise no small country could have it.
