Lingering heat wave altering lifestyles across China

Xi'an, capital of Northwest China's Shaanxi province, which has sweltered in heat for six days, saw no relief on Tuesday. Instead, it got another orange alert from provincial weather authorities.

And that's changing daily lives, including the choice of food.

As many parts of China entered into summer with temperatures above 35 C, an increasing number of people are choosing to avoid the heat and are ordering meals online, bringing brisk growth for restaurants.
