I think dao de jing is not being read among young people and common people in china nowadays.At least it isn't embodied by the national middle and primary schools' chinese language textbooks.in this case many students will not learn it in the classes.on the other hand,for dao de jing is ancient prose at all ,it is hard to read for modern people so many people often read the modern texts edition.In my eye though many people don't read dao de jing nowadays ,what one will do and look on the things are all based on the dao de jing if one is moral.Dao de jing includes some philosophy theories that are the base of the chinese culture.
