Peili was formerly the Vice-President of the Chinese Jewelry Association, and President and CEO of Beijing Diamond Jewelries Co., a company which has operations in both the mainland and Hong Kong.
Zhang met Wen when he was working in Jiuquan as part of Gansu's Bureau of Geology. Being described as a strong-willed woman, her personality is in strict contrast to that of her husband, who is fairly introverted and modest. Zhang is never seen on any official occasions with the Premier. In 2007 Taiwan's TVBS found Zhang to be wearing a bracelet worth over two million RMB (around $300,000US) at a jewelry convention.
Zhang and Wen have a son and a daughter, Wen Yunsong and Wen Ruchun.
