Let me first say that Nian Haitang is a junior, and I originally liked the pen name Haitang very much. But it has already been registered, but Haitang has special meaning to me. So I had to add the word read in front of it to continue using the pseudonym Haitang. Because I feel that although daily life is dull, there is an intriguing truth in this dullness. So I want to write down the things and feelings I experience every day so that I can recall them in the future. There are many things I don't understand every day, and I hope that while writing them down, I can gain new insights and no longer be confused. The most important reason is that my typing speed is not very fast. I hope that I can improve my typing speed by publishing articles online. If I am lucky, my childhood dream will come true.
