Online teaching has been implemented in response to the COVID-19 pandemic. Nonetheless, teaching online consumes considerable time and adds pressure to teachers' daily lives. Teachers have to not only acquire technical skills but also provide engaging instruction online. Meanwhile, privacy breaches occasionally occur in online teaching. The objective of the current study is to analyze the factors underlying the continuance intention toward online teaching beyond the COVID-19 pandemic. We use the person-environment fit theory to develop the survey for investigation. An open-ended question appended to the survey helps to gather teachers' further thoughts on sustainable online teaching. The structural equation modeling reveals that teachers' technostress is associated with their privacy concerns and self-efficacy in delivering effective instruction amid online teaching. The multigroup analysis further demonstrates that technostress, self-efficacy and school support are related to the continuance intention to teach online for teachers at distinct teaching levels to different extents. The responses to the open-ended question reveal that teachers' preference for online instruction lies in wealthy teaching resources and flexibility. Students’ learning performance and the effectiveness of assessments constitute a concern in conducting online teaching. The implications for policymakers and teachers are remarked upon at the end of this paper.

为应对 COVID-19 大流行，实施了在线教学。尽管如此，在线教学会消耗大量时间并增加教师的日常生活压力。教师不仅要掌握技术技能，还要提供引人入胜的在线教学。与此同时，在线教学中也时有发生隐私泄露事件。本研究的目的是分析在 COVID-19 大流行之后继续在线教学的潜在因素。我们使用人与环境匹配理论来开展调查调查。调查附加的开放式问题有助于收集教师对可持续在线教学的进一步想法。结构方程模型揭示了教师的 技术压力与他们在在线教学中提供有效教学的隐私问题和自我效能有关。多组分析进一步表明，技术压力、自我效能感和学校支持在不同程度上与不同教学水平的教师的在线教学持续意愿相关。从开放式问题的回答可以看出，教师对在线教学的偏爱在于丰富的教学资源和灵活性。学生的学习表现和评估的有效性是在线教学的关注点。本文末尾评论了对决策者和教师的影响。自我效能感和学校支持在不同程度上与不同教学水平的教师在线教学的持续意愿相关。从开放式问题的回答可以看出，教师对在线教学的偏爱在于丰富的教学资源和灵活性。学生的学习表现和评估的有效性是在线教学的关注点。本文末尾评论了对决策者和教师的影响。自我效能感和学校支持在不同程度上与不同教学水平的教师在线教学的持续意愿相关。从开放式问题的回答可以看出，教师对在线教学的偏爱在于丰富的教学资源和灵活性。学生的学习表现和评估的有效性是在线教学的关注点。本文末尾评论了对决策者和教师的影响。学生的学习表现和评估的有效性是在线教学的关注点。本文末尾评论了对决策者和教师的影响。学生的学习表现和评估的有效性是在线教学的关注点。本文末尾评论了对决策者和教师的影响。
