The 2017 postgraduate entrance examination was held on Dec. 24, 2016. It was the fourth time that the 75-year-old Zou Weimin from Zhejiang province took the exam. According to Zou, the first time he sat for the exam was in 2003. As he later wrote in his diary, life contains difficulties and setbacks, but there are also opportunities to make one's dreams come true. Zou fervently believes this, even though his previous three attempts at the exam have failed.
