Zhang Zilin won Miss China World in 2007 and later was crowned as Miss World 2007.
Zhang's career in modeling and pageantry started in 2003 where she participated in a beauty pageant organized by New Silk Road Modeling Agency. As a first timer in pageantry, Zhang only managed to land herself in the top 10 due to lack of experience. However, she was later discovered by the executive manager of the agency, Lee Xiaobai. Since then Zhang has graced the runways in major fashion capitals of the world including Paris and Berlin.
In 2006, she was shortlisted as one of the top ten professional supermodels during the Chinese Fashion and Culture Awards. After that she participated in Giorgio Armani's 2007 Autumn/Winter Collection show in Paris and later earned herself the title of "Top Model of the Year" from New Silk Road modeling agency.
On December 1, 2007, she was crowned Miss World 2007 at the Crown of Beauty Theatre in Sanya, Hainan. During her reign, she traveled to over 80 cities in 20 countries. Some of these countries are the United Kingdom, the United States, Russia, Mexico, Trinidad & Tobago, Vietnam and South Africa.
