In addition, the course achieved an extraordinarily high percentage of certificate acquisition. The MOOC has as of today enrolled more than 50,000 students and received a Honorable Mention in the 2017 Greater China MOOC awards among more than 100 contestants in the category of Course Design and Quality.
