Visitors in the renovated Sinan Mansions area, in downtown yesterday. As well as an open-air museum, Sinan Mansions includes 51 Western-style garden houses. Visitors can scan the QR code on 20 exhibits, and listen to introductions about them. The block was once home to some famous people, including Peking Opera master actor Mei Lanfang. Now it incorporates fashion boutiques, hotels and restaurants, and is described as a “lifestyle hub.” — Wang Rongjiang
