With this success, the Squid Game can be said that glocalisation that Robertson (1995) said that. Which is a compound word of global and localisation, it refers to success with local characteristics and has recently been used as a marketing strategy. Given that squid games have achieved a 100% Rotten Tomato Index due to the recent increase in demand for various works, it can be inferred that it is a phenomenon that plays a role in lowering the discount rate when an unfamiliar culture works positively.

Unlike conventional mass communication models, Stuart Hall(1955) argued that there is a discrepancy between the two sides in communication exchange, that is, the moment a message is produced (encoding) and the moment it is accepted (decoding). Since the fact that the success of the series does not mean a sufficient understanding of Korean culture, I decoded the encoded Korean culture according to 5 topics and produced a video explaining it from a Korean perspective. In Squid Game, except for the games such as dalgona, squid game, marbles which are revealed on the surface, there were hidden cultural things that people who experienced the era or acquired through the media would know. I selected 5 scenes including reflected Korean issues in the past, Korean food back in 1970 to the 80s, and homage scenes of Korean films and historical backgrounds. 

First of all, regular milk and bread were served, and Ki Hoon said, "No chocolate milk? I cannot drink regular milk." This is a government milk program that was implemented from 1981 to the early 2000s, and it was implemented to increase milk consumption and children's health growth for dairy farmers in Korea. There was a separate time to drink milk, and all but a few students with lactose allergies had to drink white milk without exception. The third is Sprite and eggs. The green glass bottle cider was a model of the brand Chilsung Cider in the 80s, and now the package has been changed to transparent plastic. In Korea, cider is a brand name and is commonly used as soda such as sprite, not alcohol. And the combination usually sells in a train. It has not been found since 2005 due to the installation of a cafeteria in train rooms, but the combination of trains, eggs, and cider stimulates Nostalgia.

There are scenes where characters talk about a person who people might don't know like Lee Byung-hun or Yu Gwan-soon. One scene they talk about is a scene where a spoiler was made in homage to the famous lines of the film Inside Man (2019) in which Lee Byung-hun played a role. In Episode 1, there is a scene in which Koreans guess the historic event behind the line, which is the 1st March movement, 1919. It was a public demonstration of independence against Japan.

In the squid game, many scenes are explaining the narrative assigned to each character. In episode 5, the scene of recalling Ki Hoon's traumatic past was reflected a massive dismissal of Ssangyong Motor in 2009 as director mentioned on Netflix commentary. As noticed by he mentioned "car company", there was a physical conflict between the company's union and the police at the time. In the scene where the doctor steals organs in episode 5 , it was a scene where ghost surgery by a nursing assistant . Youtuber Doctor Mike who has 8.3M subscribers uploaded a video that analyses the medical facts of the squid game as a doctor. He said it could never happen in reality, however, it happened, and it brought public opinion that surveillance cameras should be installed in operating rooms. 

As a Korean title culture, the relationship within the group is considered important. Unlike English-speaking countries that prefer to call names, Korean culture focuses on relationships with others. And various names are called it, usually classified according to gender and age, and it is called after the name. It is common for young people to call older people a relationship. For example, women are called older sisters to women older than themselves, older brothers to many people, and older sisters to men older than themselves. Because of this naming culture, age-based vertical relationships are sometimes formed, and this custom continues in social relationships, including family relationships. Some titles reflect the social hierarchy. Ali, a foreign worker, was cut off while working at a factory in Korea. Judging from his use of honorifics to Ki-hoon and Sang-woo as teacher or boss, the social position of Korean immigration workers can be confirmed. Sang-woo's line, "I'm not the boss, so don't call me that." suggests that Ali larter calls me "brother" and that they became closer. In addition to the names related to culture, the older brother, who defines social relations, is an expression of respect for the older man's "older brother." In English, it was translated into "Boss" in context. It is mainly an expression seen in a gangster culture or a specific dialect group, and is also used as a joke among male groups. As a title that reveals the group of Deoksu, which creates a hierarchy of power between people in an unrealistic space, it is a scene that shows a change in title and attitude when the person who has called Deoksu "brother" in episode 6 reversed with the line, "Brother, I must have thought you were something."
