A 36-year-old man has become known as “China’s most stubborn man” after taking the national college admission exam 16 consecutive years in an attempt to get accepted to the prestigious Tsinghua University.

Tang Shangjun took the gaokao, China’s notoriously difficult college admission exam, in 2009. He scored a mediocre 372 points out of 750, much too low to get into his dream school, Tsinghua University. He was unwilling to compromise, so he spent the next few years studying harder and taking the gaokao. By 2016, his score had improved to a respectable 625 points, more than enough to secure admission to several universities in his home province of Guanxi, but still not good enough for his chosen majors at Tsinghua. So he kept at it, year after year, ignoring all other universities, but never quite reaching the level required to get into his desired faculties at Tsinghua University.
