BEIJING: What seemed like a simple act of Peng Liyuan , China’s first lady, taking pictures during her visit to Berlin on Saturday, has now become a celebrated event. Chinese official and social media noticed she had ditched her favorite iPhone 5 for a Chinese brand, "Nubia".Peng, a singing legend, received some criticism when photographs showed her using iPhone 5 during a visit with her husband, President Xi Jinping, to Mexico last year. This time she is being applauded as an effective brand ambassador for China by using Nubia, which costs half of iPhone 5.Ironically, Peng’s move to popularize Nubia by ZTE is going to hit its rival and Chinese giant, Huawei, which is a much larger player in the mobile phone market. ZTE has jumped to the occasion posting a photograph of Peng using its phone and said: “The Chinese dream begins with using China-made goods.”Some Chinese fashion and cosmetics brand are already reaping huge benefit out of the “Peng touch” after the country’s first lady used their products during her foreign visits with her husband. Local fashion designer Ma Ke has been in the spotlight for over a year because she wears cloths made by her.
