One of my favorite past times is reading.  I really enjoy finding a good book or a new author to explore.  Do you read much and who is your favorite author?
I don't like reading but would like to start because I see that it's a cognitive process where  you have interpret symbols and get sense out of them 
That's true.  There is a lot of information that can be shared through written word.  It's important that we continue reading and writing so that we can share information with future generations. 
It's an entire means of communicating, I wonder how information would have been easily shared around the world if not for reading
That's true.  Vocalizing one's ideas works as well but not when the person you are trying to communicate with is in a different state or even different part of the world.  Reading is very important. 
reading is king of complex just as a non chinese thing mandarin is, we have to read all symbols and shape so as to get the message
Very true.  It's crazy how different languages have evolved so that some of them involve characters for reading and others involve pictures. 
I believe it has taken us almost our entire life time to get used to the process. We started right from kindergarten with nursery ryhms and is still continous because i still see words that I have to google before i know their meanings
Sounds like you love to learn.  I respect that in other people.  Life isn't about reaching a state in which you stop growing - it's all about continuous growth until your death.  Very interesting. 
Thats very true. As they say there are no right or wrong ways to reading, just flow along and interpret the way you understand
