How to contact me?
The best way to contact me is Email: Zhijun.Tan#TanZhijun.com (please use @ instead of #, I hate spams). Other tools such as MSN and Skype are not my favorites, so I would not give you them here.
Should you have any question or would like to contact with me, feel free to email me, you are warmly welcome.
I guess some friends hate boring email. Facing the overwhelming social media, you can also follow me at Twitter, Facebook or Google+ by clicking the following links.
