I had the opportunity to use the new code this morning at the subway. Thanks to Giggi I had already installed the mini program and had my wife help me read the Chinese for setup.

At the subway (east bus station), passengers were not scanning and nobody stopped them, but I scanned in anyway.

Coming back from Tuodong Lu subway station the guards were insisting on scanning both codes.

Then....
The PSB also has a second QR code to scan now.

Again, it's in Chinese only, which I can't read, and nobody could guide me through it, so they just waved me through.

Hmmm
Yesterday when I took the bus the driver was making everyone scan in.

It brought up the same green screen I've seen before, but when I checked recently used mini-programs a different one was on the top of the list.

With no (reported) community transmission in Kunming it sounds like they're ramping up prevention efforts ahead of the spring festival holiday.

@tigertiger - I may have discovered why the hospital was so busy for covid tests.

My wife was at Yan'an hospital yesterday for an appointment.

They're requiring everyone entering the hospital as a patient or visitor to have a test.

She said the line was huge. I can't see just one hospital doing this in isolation.

Thanks tigertiger.
Two questions:

1. Is the report bilingual?

I'll need it on arrival in Canada.
2. My airline friend reminded me to be sure the passport number was included on the report.

Was it?

If not, write it on the top.

@Xiefei
You've misinterpreted my comment of "I would bet you'll be the only one on the flight".

Tigertiger's requirement for a covid test was because he was a foreigner, and therefore most likely the only one on the flight.

I've been on many flights in China in regular times that were absolutely full, but I was the only foreigner.
