Horses, are born to run freely in mountain, drink spring water when thirsty, sleep and enjoying the sunshine on the ground when tired, without worry. But the fate of horses is changed since Bole(伯乐) appeared. Draw bridle on its head, put saddle on its back, tie it and the death rate of horse is up to 20%-30%. Then force it to transport things, force it to travel thousand kilometers everyday, horseshoe on its feet, and the death rate of horse is over 50%. Originally, horse is ruleless and useless, just absorb the prime of the sun and moon, suck the nimbus of the heaven and earth, inutility and inaction, and then die at the end of life. Civilizing it, teaching it ceremony, will kill it on the contrary. Do people do the same thing? We lost ourselves under the restriction of rules, follow the rules made by others all the time, force ourselves to do things we’re not willing to do, how much do we leave of our limited life?
