Several days ago, I wrote some words according to my programming experience on PayPal and iOS. I uploaded the document to Baidu WenKu and share it. Today, the response from BaiDu censors is that the document is an advertisement one and is not to be shared. I am very angry about the Non-professional actions from the Baidu.
Thus, I decide to share my most of tech or book-reading document on the Dropbox. It includes several Word documents and PPT documents. I hope they can help some guys who are interested in them.
