Based on the quantum social network theory, this paper conducts an evolutionary algorithm research on the law of Japanese catchphrase introduced into China and its changes in China. The network generated by this modeling method is comprehensively analyzed from the aspects of network degree, degree distribution, average shortest path, node aggregation coefficient, etc., which verifies the effectiveness of the modeling method. Starting from the language itself, from both internal and external perspectives, this paper explores the reasons for the popularity of Riyuan's animation language in China.
