Thank you for visiting my site.

I come from China. I was interested in computer when I was a student. I learned computer software science in my university -- Jilin University, the biggest one in China.
I started IT from 2002. And got the ACCP software engineer certificate in 2006. I have used many kinds of technologies until now.

I enjoy life, software, and technology. I would like to help make the world a better place. If you are a geek, or have same interests, please contact me.


As you know, music is very important for everyone in the world. It can make us feel positive and help us to relax.
I prefer electronic music the most, but sometimes I listen to pop music, too.


Good movies can provide us with knowledge and can help us look at the world differently.
I go to cinema to watch movie on some weekends.


Sometimes I have a trip somewhere.
I went to Hong Kong in September, 2014. It was a good trip. I hope you like my picture.
