here "write " means "typing" or "write by pen or pencil or sth like that" . if you wanna learn to write by pen, it would be complex to explain.the best way is to be taught by others. if you like i will teach you through cam.

http://pinyin.sogou.com/ download this software, so you could type chinese

I suggest you go to www.baidu.com and type 搜狗拼音输入法 Download ! Then use it to type hanzi

first install the character sets to view / read chinese (windows XP): control panel > Regional and Language Settings > languages tab > "install files for East Asian languages". may need the Windows CD in order to install. secondly set up an Input Method or way to toggle between languages wanted to type (winXP): control panel > Regional and Language Settings > Languages tab > in "Text services and input languages" area, click details button. under details settings tab > Add > select Chinese Simplified or Traditional restart computer. this should toggle your input language on/off with CTRL + Space and switch languages with Lshift. you can change the toggle functions. An additional IME which works better than the stock windows version is google's pinyin input: http://www.google.com/intl/zh-CN/ime/pinyin/ good luck!

It's all on your Windows CD. Install East Asia fonts, then install the Chinese IME. It's in Control Panel - Regional
