On summer mornings, an "ecological market" in Jianshe township, located in Shanghai's Chongming district, comes alive with lively activity. Shoppers gather around the tofu stall, baskets of fresh eggplants line the walkways, and homegrown baby potatoes still carry the earthly scent of the fields.

Wei Saidi, a 65-year-old local resident, stepped into the market carrying a cloth bag and was greeted by a refreshing flow of cool air.

"Shopping here is such a delight. It's bright and airy the second you walk in," she remarked.

As a longtime resident of Jianshe township, Wei recalls how unpleasant the market used to be in summer. It was stuffy, and the floors around the seafood and meat sections were often damp and sticky. Today, a cool breeze flows through the aisles. Different types of produce are neatly arranged in separate sections, and the floors remain dry and clean, making shopping a far more pleasant experience.
