In this forum, I have posted several articles to introduce my points of view towards Hanzi. You should know better than many of others. Now, you seem like a new comer without knowing anything. Should I repeat what I have said before to everyone? People come and go, and I am only one person with both hands for writing. That is why I told you to look for your own answers on this topic. But let me quickly name some of fatal problems of Hanzi and this will be my last one responding to your own curiosity. Does people who thinks in Hanzi know how to find information of his or her own other than just asking for help? Here are some problems of Hanzi:

Hanzi is:
hard to learn, hard to use, can not work together with speaking language(hanyu), hard to import words from other nations, cost of education is too high, hanzi has big negative impact in people's way of thinking, Hanzi is not a good symbols for using in other fields other than using in natural language, Hanzi has no orders, which makes Hanzi information a big chaos, Hanzi information is hard to search, Hanzi is hard for word process by either human beings or by machines, hanzi is not a good carrier of information, hanzi is not good for language development, Hanzi is not good for social developement, hanzi is not good for almost everything.

Enough for you to handle for now? Let me know if you need more.

Best Regards!
