The college, in the city of Xian in Shaanxi province, uses the "commitment card" during a course called No Regrets Youth class, according to the China Economic Daily website . A photo of the card has been widely shared on Chinese social media. "I promise to myself, my family, my friends and my future spouse and children that I will refuse all kinds of premarital intercourse before I step into a lifelong monogamous marriage," it reads, with space underneath for students to sign their names. It also includes a pledge to avoid infidelity once married. While abstinence pledges have existed in US colleges since the mid-1990s, they're very rare in China.
