As high temperatures continue, people are swimming in public areas where bathing is prohibited, despite official efforts to deter them.

On Sunday, the Beijing Meteorological Bureau issued an orange alert for the second time in five days when the daytime high temperature hit 37 C. An orange alert is the second-highest in China's four-color heat-warning system.

The high temperature has seen more swimmers show up in the Kunyu River, Shichahai Lake, Yuyuantan Lake and the southern city moat.
