【正确答案】What does "Tao" mean? Tao refers to the road. The earliest road appeared on the bank as the primitive people went to drink or take water by the river. People at that time stepped on the sandy land with water on the naked feet. Thus, a trail as smooth as "刀" formed. And they just called the trail "刀", which is Tao. "Tao" and "刀" are homophonic and "Tao" was written as " 刀" in the inscriptions on bones. Since the pristine day towards today, human being has been walking on the "刀" all the time. Tao also refers to the passer-by. The road formed because of the passers-by's treading. We know that there was people's presence immediately watching the road. Tao also refers to the way you walk. There are straight road and forked road, main road and minor road, temporary road and permanent road. As all the roads undulate, twist and turn, people have nothing to choose but the devious route and meantime the shortest one. Tao refers to the arrival. Every road has its beginning and ending. If you tread the Tao(road)according to Tao(way), you will arrive at the ending soon. There is only one real Tao(passer-by), which leads to self.
