Jiangcheng in June is like a steamer thrown into a charcoal fire. The asphalt road is so soft in the sun that you can faintly hear the sticky sound of the soles of your shoes melting when you step on it. Cheng Mu rode a second-hand electric scooter and turned into the narrow alley of the old city. The take-out bag in the cart basket was wrapped three times with transparent tape, but it still couldn't block the sweet aroma of the milk tea inside, mixed with the salty smell of sweat, creating a stuffy smell in the heat.
