The following summer, Peng invited the wives of leaders attending the Youth Olympic Games in Nanjing, capital of Jiangsu province, to try their hand at Suzhou embroidery, helping to create a piece called "Silk Road."

She also led leaders' wives on a tour of Beijing's Summer Palace, an ancient royal landscape garden, during the APEC meeting, and took another contingent visiting in March for the Boao Economic Forum in south China to drink coffee and watch women making Li brocade, a textile produced by the Li ethnic group that has been listed by the UN as intangible cultural heritage.

Promoting culture is a major task for a first lady, and Peng is the perfect example, according to Ruan Zongze, vice-president of the China Institute of International Studies. "People can discover the beauty of Chinese culture through her dresses and through her ideas," he said, adding that her image is one of "confidence and decency".
