缠中说禅原著，其所阐述的缠论为最权威、最准确的。书中未添加任何他人见解，所谓“千人千缠”的说法是不准确的。就如很多人在解析江恩理论时添加了个人见解，却不能准确反映江恩理论实际，误导了很多人。同样要想掌握缠论，只有反复阅读缠师的原文及回复，找出当时的走势图并通过大量的复盘和实盘操作演练，才有可能及缠师之万一。对于想寻找捷径和拐杖的人，且不说捷径和拐杖是否正确和靠得住，就这懒惰思想，想掌握缠论并靠其赚钱如痴人说梦。 缠中说禅将博客命名为“全球第一博客”，先后发表了1134篇博文。曾预测2007年由美国次贷危机引发全球金融危机。预测2005年中国股市见底，2007年见大顶。 博主因患鼻咽癌于2008年10月31日去世，离世时还不到40岁，由于屡屡神奇的公开预测成功，所以在网络上粉丝众多。 有人说人会死三次，第一次是他断气的时候，在生物学上死了；第二次是他下葬的时候，人们来参加他的葬礼，怀念他的一生，然后他在社会中死了；第三次是最后一个记得他的人把他忘记的时候，那时候他才真的死了。 虽然缠中说禅已不再更新博客，但是他把他的神奇留给了市场，留下了精彩的教你炒股票系列，每天有成千上万的缠迷在学习他的缠论，他的思想。
