Leaving behind the 996 grind in the city, Fang Qinan returns to his hometown to renovate his ancestral home, embracing a pastoral life of tending flowers and plants and filming short science videos about botany. Unexpectedly, his neighbor Li Fucai builds a pigpen right against his courtyard wall. The foul stench withers the flowers and plants in the courtyard, and when he goes to negotiate, he is met with arrogant refusal. When reasoning fails, Fang Qinan devises another clever plan: he plants a large amount of pungent peppermint in his courtyard, using its fresh fragrance to neutralize the foul odor and force the other party to back down on their own.
