淡然一切往事如烟
        
            [dàn rán yī qiè wăng shì rú yān]
        
        
            'As light as mist and all past events are like smoke.' This expresses a serene attitude towards life and history, indicating a wish to view past occurrences with calmness, letting bygones be bygones, and emphasizing a state of mind where past grievances have faded away gradually.
