I think there has been a major miscommunication somewhere. I checked with a friend who i the GM of a Crowne Plaza hotel in Chongqing.

She had a look at the official notification from the government which they received the other day.
The requirement is for 48 hours testing before interprovincial travel (by plane, train or automobile).

There was not mention of 24 hours for anything local.
Does anyone in this group have access to either Yunnan or Kunming government websites to see if there is a local policy?

This article on GICExpat dated Sept 9 indicates there is a China wide 48 hour testing requirement for subways, buses, etc.
I'm bothered by this statement "passengers must present a negative nucleic acid test certificate within 48 hours before boarding planes, trains, buses or other means of transportation." which doesn't define what those other means of transportation would be.

Do I need a covid test to take a taxi?

Do I need a covid test to get in my wife's car?

Nobody in my wife's very large community group knows about these new restrictions.

It appears they only apply to expats.

Strange.
A friend phoned the subway admin office for me yesterday (9-10) and was told there was "no need" for the Covid test (yet).

She also reported that they weren't enforcing it strictly (yet).

Meanwhile, my wife's community group has not reported this either.

It sounds like communication of the rules is not consistent, even within those areas that are supposed to monitor and enforce.

If a 24 hour negative test result is required to board buses or subway, how does anyone get to the testing places?

They're not all local, we don't all drive, and we don't all use Didi.

There are just 18 confirmed cases in Kunming now yet they're getting close to locking down more than 3 million.

So if I'm reading this correctly, the entrance to VC Park next to the Korean BBQ and Metro north has strict controls, but the entrance from the subway or street level by Beijing Rd is NOT controlled?

That sounds a bit like they're trying to protect the residential units rather than the shops but it's still kinda dumb.
