I wrote the following blog while I was in Wuhan, China, during my vacation. For some reason, I could not access to my blogger there. I had to write my blogs in my sina blog. Now I copy the blog back to my programming blog.
I had to write my English blog at Sina blog web site since the Blogger is not accessible, during my visit to my extended family in Beijing and Wuhan. Fortunately, I have a Sina blog account so that I can continue to write my blog. I'll copy this blog to my Blogger when I get back.
