The main content of "Decoding the Beijing Food Code" revolves around Chinese food culture. Through the visits and attempts of two hosts to well-known Beijing restaurants, it allows overseas audiences to learn about Chinese culture and language through food. For example, in this season, we not only visited famous restaurants such as the traditional "Cuihualou", "Lijia Cuisine", "Gongdelin" and "Xiaodadong", famous for innovative dishes, to let overseas audiences know and understand famous restaurants in Beijing, but also compared Beijing food with similar overseas food through "Zhajiangmian", "Instant Noodles", "Barbecue", and "Dim sum". In addition, traditional Beijing food such as "fermented sour milk made from ground mung bean wow gold" also entered the host's vision and made a try.
