Gonjiam: Haunted Asylum behind the scenes gags

The owner of Gonjiam: Haunted Asylum requested the court to ban the film from being released. Therefore, the beginning and end of "Gonjiam: Haunted Asylum" are written with subtitles stating that this film has nothing to do with specific characters, companies, teams, and buildings   .

Some viewers analyzed from the scar on Ji Hyun's arm that Ji Hyun was the ghost who led others to Gonjiam: Haunted Asylum. Director Zheng denied this hypothesis   .

Many details in the film are reminiscent of the shipwreck of Shiyue. Director Zheng revealed that he originally planned to set Room 402 to No. 416. The filling of room 402 with water was also because of the tragedy "like a shadow in my heart   . "

In the film, the Gonjiam: Haunted Asylum Mental Hospital opened on May 16 and closed on October 26, which corresponds to the 5.16 military coup and the 10.26 assassination incident when Park Zhengxi came to power. The final hits of the YouTube live broadcast in the film are fixed at 503, which is the prison number of former South Korean President Park Geun-hye. In addition, Park Young-ae, the director of Gonjiam: Haunted Asylum Mental Hospital, is also reminiscent of Park Geun-hye. Director Zheng admitted that the Chinese character of the name "Park Young Ae" means "the daughter of the president", and the old photos of the dean playing table tennis also refer to the photos of Park Geun-hye playing table tennis. The camera angle is exactly the same   .

In an interview, Director Zheng said that the film has an ultimate easter egg. If no one finds it, he intends to say it before he died   .
