For 2019, I decided to write again. but I couldn't still insist constantly. In the end for 2019, I found it only had 56 chapters for two years. I felt it was a little. I wanted to make myself write every day, but it wasn't easy to do every day, sometimes when the work was very busy, it forgot easily. I found the function for the challenge to update every day in Jianshu. So i chose to challenge in February for 2020, when I chose to do so, it seemed to have a monitor for me. The updating every day became my a task. I must do it every day, otherwise i felt that i lost a thing. I insisted in writing every day, it made me felt to have some change for these days. Today it is the fortieth day for me to update. I want to record and remember. I will continue to insist. Someday i will also share the experience at here. I also hope i can update the English blog every day.
