Sorry for being no update a long time. Since my sites including here were hacked last year and I have been busy in switching host recently.
If you are a frequent visitor to this site, you may know I have updated some pages but the more important is that more updates are coming soon. So, I reinstall the update blog and let you know the updates clearly. Besides, I re-activate the commenting system, hope the anti-spam can do its job. Then I can have more interactions with you.
And you can subscribe for the update feed by saving the rss feed in your rss reader.
Okay, it’s time to continue my job. Talk to you soon.
