The referee Jin Xikun's penalty in the match between Luneng and Guoan caused huge controversy. Regarding the refereeing ability of South Korean referee Jin Hekun, a long-term concern about South Korean football bloggers said that South Korean Jin Hekun was promoted last year as a South Korean special referee. He was a sports teacher in middle school before and the referee was just a side job.
South Korean football blogger said on Weibo: "Kim Heekun was promoted to the South Korean special referee last year. Before that, he was just a sports teacher in a Korean middle school, and refereeing was a side job."
"To be a joke, his level of education is not as good as that of Chinese referees, so it is not suitable for him to check the papers."
