This article explores the life of the professors of National Southwest Associated University during the Anti-Japanese War in detail,and tries to reveal their mental outlook and their enlightenment on how to live.The paper also describes the daily lives of Professor Zheng Tianting and his colleagues,including living and sleep,body care,diet and hobbies,family life,closeness to nature,appreciation of cultural artifacts,various cultural and entertainment activities,nostalgia for deceased relatives,communication and care within clans and social groups,diary writing,and self-cultivation.Zheng and his colleagues from National Southwest Associated University felt deeply that people living in social groups needed to take the initiative to find friends,make friends,and be critical friends.Friends can encourage each other,solve difficulties,promote personal development,enrich life interest,and improve quality of life,which makes an already active life more dynamic and colorful.The life of Zheng and his colleagues was in accord with the social conditions of the times.There are three aspects of consistency between them: the common experience of war,patriotic spirit,and confidence that China would definitely win;traditional moral benevolence and the inheritance of the spirit of the ancient Chinese intellectuals who cared about the country and the people before personal enjoyment;and maintaining the spirit of the times,which was a new awareness of independent personality and consciousness.There are many inspirations for life that can be drawn from the daily life of Zheng and his colleagues: People should have a rich and diverse life,every meal deserves to be taken seriously,and one should watch art performances,play mahjong and poker,appreciate art works,collect cultural relics,and so on.Such is what life should mean.Whether it was the willingness of the professors of National Southwest Associated University to go Dutch when they had dinner parties during the Republic of China or the novel experience of daylight savings time,these were considered new things in life.They are a reminder that we need to continue to supersede closed thoughts.The professors,who had both the essence of traditional morality and the mod sense of democracy,realized their desire to be their own master.
