However, the Chinese language has evolved alongside the characters for about 3000 years, and it's very difficult to just separate the two. A huge amount of culture is bound up with the characters. Not only that, but the Romanized writing system is viewed as something that only little children use (as an aid to learn the characters). Once you've put in the effort to learn the characters (as about a billion people have), it's very difficult to accept their replacement by what is viewed as a script for children.
