For a fee, students can fake their internships

As junior students in Chinese colleges take on summer internships, some unscrupulous businesses can't wait to make deals - like selling them fake internship certificates online.

For many students, internships are part of their course work and are directly connected with school credits. In 2015, the Ministry of Education issued a notice requiring that internships should account for at least 30 percent of all credit hours. Schools typically ask students to take up internships for a few months to prepare for future careers.

But if the students don't go along, there is an easy way out. For just 200 yuan ($30) or less, you can get whatever internship certificate you like online. The business is obviously illegal, but it exists nevertheless.
