Test Heater Even in Summer — Winter Discoveries Hurt

Test Heater Even in Summer sounds like a micro-optimization until you are on a Didi ride through rain that turns Chengdu traffic into performance art.

A taxi driver who refused small talk until I mentioned food once stood in pepper steam for twenty minutes because I misread the lunch rush. The fix took less time than telling the story.

Try this once: write the rule on your phone lock screen for three days. If it survives, it is yours.

Works for me in Chengdu humidity.
