A 72-year-old Chinese man has become an internet sensation after his granddaughter used him as a cross-dressing model to promote her clothing store.

Lu Qing, who lives in southern China's Guangdong province, posted pictures of her grandfather dressed in an array of pink skirts, red tights and fur-lined women's jackets to promote her online fashion outlet Yuekou.

The images of Liu Xianping have since gone viral and seen him branded the “world's coolest” grandfather by internet users for his slender legs and modelling poise. They have also boosted his granddaughter's bottom line. - AFP
