A kind of sinuous scarlet bench, the Red Ribbon snakes for half a kilometre through Tanghe River Park, a reclaimed green space in the Chinese city of Qinhuangdao. Four pavilions are dotted along its dragon’s-tail length. They consist of white canopies in irregular, ink-blot shapes – stylised clouds, perhaps – where you can rest in the shade and contemplate the silver strip of the adjacent river. But the Red Ribbon, designed principally by Kongjian Yu of Turenscape, is more than an attenuated place to sit: it is also a children’s climbing frame and a walkers’ path. And it is at its most attractive and spectacular at night, when it glows like a tightly packed string of Chinese lanterns.
