In Nanjiichi's words, he revealed: "In my country, true brothers are often made at the drinking table, so I pride myself on tasting baijiu with a strength of more than 50 degrees. Many Chinese fans tease that this is the essence of what he has truly learned. South Korea may not have a strong alcohol culture, but the hierarchical relationship in the society is very strict, and so is the drinking and eating. If you want to participate in drinking, you have to be qualified to enter the table, otherwise you can only be a servant to accompany the drinks and serve food. Korean society is very hierarchical, and the younger generation shows respect when they meet their seniors, and this is especially true at the drinking table. The younger generation is expected to raise their glasses and even drink before their seniors, showing humility.
However, during Nam's coaching career, he also had frequent disagreements with Chinese coach Yang Chen's team. According to media reports, Yang Chen and Nan Ji Yi had many disagreements, and Nan Ji Yi repeatedly told Yang Chen bluntly that he was not allowed to step into the locker room. From this, it can be seen that Nan Ji Yi is also a coach with a strong personality. In the face of Nan Ji Yi's tough attitude, Yang Chen had no choice but to resign and bid farewell to the Henan team. Along with Yang Chen's departure, Li Wei Feng of the Chinese coaching team also left with him. During his tenure at Henan, Li Wei Feng not only suffered a huge setback in his career, but was even seen as a symbol of failure compared to Xu Jiamin. The addition of Xu Jiamin to the team epitomizes Li Wei Feng's management of Henan. In addition to Nasario and Maidana, there are two other foreign players.
