Unfortunately, during that round in 2021, including this round in 2024, the investment research KOLs that surged are mostly not updating much. Recently, I followed a few new KOLs who are still fighting on the front lines and looking at projects every day. Which investment research KOLs with good content can I follow? Both Chinese and English are acceptable, no limit on the number of followers, mainly just need in-depth investment research content. I need to learn from the post-00s.
