You can to my blog where I have Chinese stories on culture etc to share for those wanting to learn Chinese and her traditions. http://jeffinous.blogspot.com

I think you can start with the things around you like cookies , pets , families what will Chinese think talk , I prefer real human than books , you just find some partner chat with each other like what you do with real friend and listen to Chinese news watch TV shows do as a Chinese do .The environment will tell you the Chinese culture naturally .

i think you can start from chinese idiom (成语). my suggestion is to buy a Concise dictionary of idioms,it won't be too difficult. if you need a certain topic , i think "chinese traditional festival" can be a good topic to know some culture of china. أتمنى لك التوفيق

What are you interest in ?It is a really big topic!

I think you may begin with some introductive readers in Arabic or English, there may be some free ones accessible. Try this website: http://www.hanban.edu.cn/resources/ There have once been several series of course books open to download for free. you may ask the officials of Hanban about where to download. You can print them based on the electronic version. After having basic knowledge of Chinese language and culture, you then can start learning Chinese language.
