Get the following: Heisig: Remembering the Simplified Hanzi This will solve all you Chinese Character problems.

My English is not good.Hope you can understand. That's very interesting.Chinese child learn to read the hanzi before their kindergarden.For example,you know "大" reads "da",and "天" reads "tian". Then,parents teach them to write them.I meam the simple hanzi.children's written is always ugly.Then,the teacher teach them pinyin like a o e i u v b p m f etc. in kindergarden.The children write them.After that,children learn to spell pinyin. Children ask parents how to read one hanzi before they learn pinyin,but after they learnt pinyin parents never tell them how to read.Instead of,children spell it on their own.Then,they can read it and try to write it. Well,this is how a Chinese child learnt hanzi. :-)

first learning pinyin，then chat with Chinese.

You are quite right, pin yin is easier way for your learning. for each outsider, grasp the firm basement of language which means you can learn whatever you want to get anytime. Here is question for you,' what do you want to learn?'

Yes ,you should learn pinyin at first.Otherwise,it is dificult to learn pronunciation. And then,You should learn Chinese characters one by one. Besides,you should practice writing in every day.Then you can remember it.
