With summer heat cranking up to full blast, outdoor workers—street cleaners, delivery riders, parcel couriers, garden maintenance crews—are still out there, holding the line under a blazing sun. To send a real dose of cool relief to these heat-braving heroes, Lin’an District has rolled out its annual “Mobile Tea Stand” campaign—and this is the fifth year running.

Put together by the city’s Administrative Law Enforcement Bureau’s Sanitation and Solid Waste Center, Lin’an District Comprehensive Administrative Law Enforcement Bureau, and a number of socially minded cleaning companies, the mobile tea stand operates on a two-track model: fixed rest stops for cooling off, plus roving vans that bring refreshments directly to workers on the go, covering multiple streets across Lin’an. Over the past five years, what started as a simple cup of tea has evolved into a full-fledged dual-service system—a steady, seasonal ritual that pays tribute to everyone who keeps the city running through the summer swelter.

This year, the campaign has mapped out ten service routes covering Lin’an’s downtown area and the Qingshan Lake Science and Technology City. Ten service teams, each with over a hundred volunteers, are deployed with dedicated vehicles, turning them into mobile convenience points. During peak outdoor work hours, these vans cruise through major work zones in the city center and the Qingshan Lake area, loaded with iced tea, bottled water, and ice pops, handing them out to sanitation workers, road crews, and traffic officers on duty.

On top of the mobile delivery points, the campaign has also set up 14 fixed tea stations at various service stops—including the Tangning Jun, Datang Road, Wushu Street, the Service Point at No. 8 Siqian Road in Qingshan Lake Subdistrict, and the one at No. 536 Tianzhu Street. All these stations serve free homemade tea and bottled water throughout the day, and are fully stocked with heat-relief supplies like herbal anti-heat oral liquids and cooling balm. Street workers can drop in any time during their breaks, grab a seat in the AC, rehydrate, and take a proper breather.

Wang Guijuan, who’s been a street cleaner for over three years, is a regular at these cooling stations. “They’ve got air-con, they’ve got tea—when I’m tired, I can just rest here without having to hunt for someplace to escape the heat. Working as a cleaner in Hangzhou is actually quite nice,” she says, cup in hand and a smile on her face. “We just want to keep the streets clean—can’t let down all the kindness and care people are showing us.”
