This paper collects data on teaching resources and traditional cultural elements for the Chinese language teaching abroad platform and mines and analyzes the behavior of teaching Chinese as a foreign language. The association rule method is employed to analyze the correlation between Chinese language teaching and traditional culture based on the teaching data. According to the data, New Year’s Snacks (87.83 million) is the most-watched teaching video on YouTube, followed by Lotus Leaf Glutinous Rice Pork Ribs (67.74 million). Chinese cultural symbols (a total of 100) and Chinese cultural and artistic symbols were used more frequently (a total of 54), and optimal teaching aids were selected for different categories of Chinese cultural symbols. This study successfully explored the association relationship between traditional culture and Chinese language teaching to foreigners, providing a basis for the synergistic development of the two.
