In today's digital era, character design in video games has become a new carrier of cultural exchange, and has profound significance for the construction of cultural identity. However, at present, most of the game groups and the public do not pay much attention to Chinese traditional culture. Nowadays, there are endless games, and various characters in the game have gradually appeared in everyone's field of vision. Among them, there are also characters full of traditional cultural heritage such as Zhong Li and Walnut in "The Original God. In order to better carry forward the traditional culture and build cultural identity, the design aims to creatively integrate the twenty-four solar terms of Chinese traditional culture with the characters in the game "Original God", and combine the customs, natural characteristics and cultural symbols of each solar term to design the second role of the game characters, so as to show the charm of Chinese traditional culture to more groups.
