Create a BLOG is easy, and BLOG is very useful. I have applied for two BLOG, one is in Chinese and the other is in English.
I choose the English BLOG eventually, because it is hard to connect my Chinese BLOG, and the view of my English BLOG is better and it is full of functions, such as changing the template by writing code.
I can look at other people’s BLOG one after one by a click. It just like change the channel on TV, you will not know what subject comes out in the next channel. This is a free experience, like shopping, you can come across so many new items.
