The aim of this study was to determine Thai adult learners’ attitude toward learning Chinese culture among beginner, intermediate and advanced level, in order to identify whether there was a significant difference among the levels. This study was conducted at a Chinese learning center in Bangkok, Thailand. The study focused on 210 Thai adult learners in a Chinese learning center. They were 100 learners at beginner level, 60 at intermediate level and 50 at advanced level. The researcher used the descriptive statistics and one-way ANOVA to analyze the data. Thai adult learners had positive attitudes toward learning Chinese culture in Chinese as a foreign language class. The result of a one-way analysis of variance showed that there was no significant difference among the three levels: beginner, intermediate and advanced, as the significance was higher than .05 (p > .05). Based on these findings, the researcher gives some suggestions to learners, teachers, school administrators, curriculum developers, and future researchers.
