It has been more than seven years since January 1, 2011, which means more than seven years of work.
After wandering in Beijing for seven years, I have accumulated a lot of technology. I may forget the technology slowly. Looking back at the blog I wrote 7 years ago, it is still very refreshing. The habit of recording every bit of life and learning is still very good.
A good memory is not as good as a bad writing, so I will clean up the blog again and let everyone encourage each other.
