This is my first blog. This is my first post. I regreted that I started so late. In 2000, the late Professor Samuel T. Chanson told me to start a blog. I did not. In mid 2007, I created a blog by Hugo and Jekyll. I posted some messages and I stopped. Now, I created another blog by Blogdown. Thanks to Yihui Xie and Alison Presmanes Hill.
The purpose of this blog is to summarise my current and past reading.
