As for me, nature is the best palce to relax. With fresh air and beautiful sceneries around, all the bad mood and tired feeling will disappear in a second. This reminds me of our ancestors who came out of the mountains and forests, followed their dreams to build cities and develop civilization ,but finally wouldn't made them to be as happy as they preconceived. The city life usually gives me a feeling that I am just like a passer-by here, my root is not here, there is a calling always sounding in my mind which makes me really want to go outside and enjoy the nature. Sometimes I really don't understand the purpose of developing technology, and what the technology can bring us? It feels like that we have lost something that is most important to us and try our best to pursue something that are not that important. That's why the people live in this era have been becoming confused and frustrated more. Only spending a little time in nature can give us a short period with peace. then we are forced to go back to city and be as busy as a bee.
