Preface
I have been living in the United States for many years, but due to laziness, I have never written anything. Recently I met a very talented netizen, and with her encouragement and influence, I also wanted to record some of my feelings, so as not to feel like my years were wasted in the future. They say time flies like an arrow, but time in the United States probably flies like a rocket. The past twelve years seem like only one day. When I return to the mainland, it feels like one day in the sky and a thousand years on the earth. When I went abroad, there was no Internet, so it was difficult to quickly share my journey with others.
