**My Journey in Electronics: From a Child to an IC Sales Engineer**
From the time I was a child, thinking that electronics was just a radio, to becoming an electronic engineer, and now an IC sales engineer, it has been almost a decade. Of course, my real work experience is about three years. I want to share my story with you, not just for bragging, but also to help you understand what it takes to build a career in electronics. I'll talk about my personal journey, my English learning, and my professional experiences, and give some insights into what kind of knowledge is truly useful in this field.
I believe that being "qualified" isn't about how much you know, but whether you can get a job. Many people say they're qualified, but if they can't find a job, then they aren't really. So, I'm sharing this not just to show off, but to help others who might be on a similar path.

**First, My First Encounter with Electronics**
When I was young, my family wasn’t wealthy. Many kids in my village didn’t go to school; instead, they went to Shenzhen or Dongguan, where electronics factories were booming. Those jobs offered better pay, and I dreamed of working in one. But my parents stopped me from going. I ended up finishing junior high school and being the only one in our class who continued to high school.
In high school, the goal was clear: to get into university. Teachers constantly reminded us that studying hard would lead to a better future. I used to tell myself that I needed to study hard for my wife, which became my motivation. At the time, I was fascinated by the WAKEMAN tapes and the headphones. I even tried to repair them, and I remember a classmate who could fix them. He became my hero, and I followed him around, trying to learn from him.
Eventually, I learned to fix WAKEMAN tapes, and even took one home after getting married. It was a small step, but it sparked my interest in electronics.

**Second, College Days: Soldering and Learning**
I finally got into university, majoring in Electronic Information. The first year was tough, with courses like circuit analysis and Marx theory. I struggled, but I found a way to connect with others. I joined the Electronics Association, where I first learned about ICs.
In my freshman year, I soldered a simple power supply circuit. When I successfully powered up the 7805 regulator, I was thrilled. That moment made me realize the joy of building things. Over time, I improved my soldering skills and began understanding more complex circuits. I started recognizing common ICs like 74138, 7447, and 7805.
During my sophomore year, I took courses in digital electronics and microcontrollers. I was particularly interested in single-chip computers. Although I initially felt lost, I eventually caught up by drawing internal diagrams and memorizing code. I even participated in a provincial electronics competition, which was a turning point in my academic journey.

**Third, A Summer of Growth**
In the summer of 2003, I joined a summer program led by Professor Lao Bao. It was intense—working long hours, learning Protel and C51, and completing projects like a stopwatch and MP3 player. It was exhausting, but I gained valuable hands-on experience and improved my technical and organizational skills.
This summer was unforgettable. It pushed me to my limits, but I came out stronger. I realized that success in electronics comes from dedication, not just talent.

**Fourth, Job Hunting and Interview Experiences**
After graduation, I focused on finding a job in R&D. I prepared a portfolio of my projects and had Lao Bao recommend me to a company in Shenzhen. During the interview, I explained my experience and demonstrated my work. I was hired as a technician, and I quickly learned the importance of market-oriented design.
Working in after-sales support taught me a lot. I had to troubleshoot complex issues, and I learned practical skills like using zero-ohm resistors and flying wires. These experiences shaped my understanding of product quality and customer satisfaction.

**Fifth, Learning English the Crazy Way**
English was always a challenge for me. In high school, I hated it. But in college, I discovered the "Crazy English" movement. I joined a training camp and eventually became its leader. We practiced shouting phrases until we could speak confidently. This experience helped me improve my communication skills, which proved invaluable in my career.

**Sixth, My Career Shift to IC Sales**
After working in electronics for over a year, I read an article about the future of electronic engineers. It made me think about my options: joining big companies, starting my own business, or going abroad. None of those paths suited me. I decided to move to Beijing and become an IC sales engineer.
I was hired by a company in just a few days. I was introduced to ADI’s magnetic coupling isolators, which fascinated me with their high performance and potential in the Chinese market. My boss, a young and brilliant engineer from Tsinghua, inspired me. Working with him was a dream come true.

**Conclusion**
My journey has been filled with challenges, growth, and unexpected opportunities. I’ve learned that passion, persistence, and continuous learning are key to success in electronics. I hope my story helps others on their own paths. Stay curious, keep learning, and never stop exploring.
