One way of justifing the celebration of man and nature, or better to say man and nature through mountain, is that

the urban people feel their lives are shallow and their experiences inauthentic. It is as if all reality and our humanity has been absorbed into the a crowded city without ethics, leaving individual left with nothing but series of chains. It is as if a sense of reality has been stolen from people. So, people try to to find out, try to look for that sense nowhere but in the mountain, in the peak. This is the reason for the celebration of the people with nature.
