Pin Landlord WeChat for Repairs, Mute for Spam

Pin Landlord WeChat for Repairs, Mute for Spam sounds like a micro-optimization until you are in a Jinjiang apartment where the dehumidifier runs like a second roommate.

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.
