The psychological well-being of educators is imperative, especially when navigating complex career dynamics such as China's "up or out" policy. This research investigates the well-being of women L2 teachers across various Chinese educational institutions. Utilising a multiple linear regression model, the study unpacks relationships between system-related teacher anger, work engagement, teaching enjoyment, job satisfaction, emotion regulation behaviour, and overall psychological health. The result shows a strong positive link between work engagement and emotion regulation behaviour. Moreover, job satisfaction is pivotal to emotion regulation and psychological well-being. By highlighting the profound influence of emotion regulation, this study provides essential insights into China's unique educational context. The results offer valuable directives for policymaking, educator training, and institutional practices, all aiming to fortify the psychological well-being of L2 teaching professionals.
