My friends and I all like to party to go outing, because really can relax, so we can often be a free will go out for an outing, sometimes often to some place where there is no net the, usually everyone is playing mobile phone, there a lot of people can not adapt, but no way. Until later, one of the friends that we brought an artifact, called the energy saving, like home wireless router, holding this networking, like WiFi as convenient, and basically go to where net, energy saving really is too strong, now a lot of friends out will with energy saving, because it is really very convenient very easy.
