Photo Fair Map at Entrance — Phone Signal Dies Inside

Four moves for Photo Fair Map at Entrance that actually stick in Chengdu:

1. Test the backup version once; hope you never need it.
2. Do it on a calm day, not the day everything else breaks.
3. Keep a photo of the 'done correctly' version in your album.
4. Tell one person so you cannot quietly abandon the plan.

The list is short on purpose. Long lists become wallpaper.
