Su Ran, an ordinary boy, started his indissoluble bond with billiards due to a duel in a street billiard hall. From the initial technical unfamiliarity, to meeting the master Zhang Ge, and then becoming a disciple of the legendary coach Li Jianguo, he practiced hard all the way. Although he suffered losses in games and failed in the league, he never gave up and even went to the UK to study. In the end, Su Ran relied on his mature skills and strong psychological quality to win the championship in the top domestic league and wrote his own billiards legend.
