In June 2013, Rui Chenggang interviewed South Korean President Park Geun-hye. After the interview, Rui Chenggang asked Park Geun-hye to take a group photo and ask for an autograph.

During the conversation, Rui Chenggang directly called Park Geun-hye "Sister Park" in order to build a relationship. This may have caused Park Geun-hye's displeasure. He said bluntly: "You are very smart, but remember, don't put the country at risk." "The word is used as a prop for personal desires."

But Rui Chenggang seemed to be unaware of it. Faced with Rui Chenggang's enthusiastic request for an inscription, "Sister Park" wrote a line in Chinese characters: "Rui Chenggang, live in this world." , I just want peace of mind.”

The well-intentioned warning of this inscription is not difficult for ordinary people to see. It is to "encourage kindness" to Rui Chenggang, rather than to praise him. Pu's inscription directly mentioned Rui Chenggang's name. It can be seen that this inscription was unambiguously addressed to Rui Chenggang, asking him to behave well.
