The first time I met Teacher Fengmi was probably in 2021. At that time, Teacher Fengmi was still in Shanghai and in the @ cryptocishanjia group. The three of us had barbecue, and we admired Teacher Fengmi's professionalism at that time. It was probably the earliest version of "sitting idle" and had to be manually completed in the face of a lot of interaction. In the early days, petting cats was really a tough job, how hard it was. After half a year of learning, Brother Naizi and Teacher Fengmi couldn't hold on anymore, and I didn't even dare to try. Today, Teacher Fengmi is no longer just a synonym for cat lovers, but has strong insights in DeFi and public blockchain fields. It is not an exaggeration to say that Teacher Fengmi is likely to be the second super champion and bring out the second essence community.
