I started writing blog posts to share with people online. Alongside that, I began organizing materials derived from my work and academic experiences. Whenever inspiration struck, I felt driven to share noteworthy ideas through my writing. It was during this time that I also started incorporating software development into my career.

I decided to rename the blog to create a vivid depiction of the daily life of an engineer. During this period, software work consumed a significant portion of my life. I actively collaborated with others, co-authoring and translating software books to enhance my skills. This effort proved invaluable in advancing my expertise in the field.

My passion for E.E. remains undiminished. During this phase, I also dedicated effort to creating a Chinese version of The Tao of Phasor series courses. The response was incredibly positive, and it achieved significant success.

Throughout my career, I have found great enjoyment and faced exciting challenges while building my software skills. Building and launching a product alongside my colleagues has been the most meaningful experience for me.

However, during this phase, I experienced a sense of confusion as I struggled to define my professional identity. And that is precisely why I decided to rename my blog as “Engineer Undefined”.
