According to Chinese business magazine New Fortune, Zhang made the magazine’s yearly ranking of the top 500 richest people in China along with her husband, making her one of China’s youngest female billionaires at the age of 24. Liu, whose net worth is around US$11.6 billion, also ranks number 16 on Forbes’ China Rich List. Zhang has been actively promoting JD.com’s luxury portfolio as well as the e-commerce giant’s public welfare projects. She has also invested in a variety of companies such as Uber as part of Liu’s family fund portfolio. In March, she met with Bill Gates at the launch of JD's public goods fundraising platform. In April this year, Zhang represented JD at the American Apparel and Footwear Association Gala. More recently, she attended red carpet events during the Cannes International Film Festival.   Same day of the launching of donation material-raising platform at JD, I joined dinner with Mr. Bill Gates!!!
