再见了，北京！                                                                       
 再见了，清华！                                                                       
 再见了，亲爱的老师和同学们！                                        
 返程的列车开动了，  缓缓驶离北京西站，                    
 让我们作最后的道别。                                                          
 聚是一团火，散是满天星。                                                 
 带着初心而来，担着使命而归。                                        
 七天的国安培训，立意深远，入脑入心。                      
 面向世界，着眼未来， 规划发展，                                   
 从容应对百年未有之大变局。                                             以史为镜，勿忘国耻。                                                              和合理念，体现大国担当。                                                  
 以人民为中心，维护祖国统一大业。                               
 回归教育本真，基础教育先行。                                        
 道阻且长，行则将至，且行且珍惜。                               
 最后，祝愿伟大祖国繁荣昌盛，                                        祝愿各族人民幸福安康，                                                       
祝愿子孙后代未来可期！                                                       
再次感谢16位组长和两位班主任为我们提供的优质暖心 服务，                                                                                          感谢清华大学继续教育学院贡献的智慧研训体系，     
水木清华的育人理念，                                                           总体国家安全教育观，                                                           将在祖国各地向下扎根，向上生长！
