I have moved Li Xiang blog from http://hiang1211.blogspot.com/, powered by Blogger, to our domain called http://onezero24.net/, powered by WordPress. I have imported all the post successfully by NOT using the default WordPress importer (WP-Admin -> Tools -> Import -> Blogger).
What I did was to make a backup of the blogger site (Blogger Admin -> Settings -> Basic -> Blog Tools -> Export Blog) and then it will generate a XML file for you to download it to your PC.
