The Time Events and the Poetics of Care for the Oceans
《Journal of Philosophy Study》2019年第9期544-552,共9页Emily ShuHui Tsai 
The images of the oceans often inspire us to take a poetic lift of the spirit for an escape from the daily boredom or troubles related to the social restriction based on the ideological hierarchy.On the other hand,how...
