It has been many years since I came to Beijing, and I have long wanted to write something to commemorate my lost youth. However, I have always suffered from a busy work and no time, and also because my thoughts are too busy and I have no chance to settle, so I have never started writing. Today is the tenth wedding anniversary of Da Niuzi and I. I take this as an opportunity to record every bit of my time in Beijing. While this memory is still clear before I enter my forties, it can also be used as a periodic summary of my life. I have to admit that coming to Beijing was indeed the most significant turning point in my life. I plan to record every bit of my time in Beijing through memories, so as to encourage all my brothers and sisters who are struggling in life.
