$Invesco QQQ Trust(QQQ.US) Recently, I've seen many people in the community discussing Er Dai, Brother Kun, and LuYouyou. Coincidentally, I follow all three of them. One of them is my mentor. We met in April 2025, and I was probably one of the first people to know him on Longbridge. So, I think I know a bit more about Er Dai than other friends. In April 2025, during the tariff war environment, the $SD GOLD(01787.HK) stock I bought got trapped. That was my first trade when I entered the stock market. I was really scared at the time and shared my plea for help in the comments section. Only Er Dai replied to me then, telling me not to worry and suggesting I try day trading to lower my cost. That was the beginning of our acquaintance. Many people see Er Dai now with a high win rate in the battle of weekly options and think he's not real. Actually, before May 2025, Er Dai was mainly trading $XIAOMI-W(01810.HK) in the Hong Kong market. He was very good at day trading within Xiaomi. Every day when he traded, he would teach me his day trading methods. Because I was new to the stock market and knew nothing, he became my guide into the stock market and later my mentor. He started exploring US stocks in late May 2025. He told me he was going to try US stocks. The US market is more volatile. At first, Er Dai only dared to buy shares, one by one. He would be very happy making $50 or $100 trading until around midnight. Slowly, by the end of June, his mother didn't agree with him continuing to trade stocks and wanted him to work steadily. He faced a choice then: follow his parents' arrangement or secretly continue trading. Of course, Er Dai later chose to persist. It was also around that time he got into meme stocks. Many friends know that Er Dai's start was due to meme stocks. At first, his account was halved, he got margin called, and was anxious all night. I was too busy with work at that time to follow his trades, but we kept in touch via messages. I remember clearly one morning he excitedly told me he hadn't slept all night; that night he made 180k. That was the first time I saw him so excited about overnight trading. Not long before that, he had just been anxious because his account was halved. I have to say there's a reason for Er Dai's success. At that time, he was still working. Although the work wasn't busy, he maintained a basic routine. Er Dai traded Hong Kong stocks during the day and US stocks at night. Pre-market, night session, after-hours—he was always ready to catch meme stocks. He didn't have many hobbies; his only hobby was reading novels and listening to music. How many people can maintain that level of focus? Later, he succeeded. He started exploring options in late August/early September. The first time he bought weekly options, he knew nothing and lost everything. He asked friends everywhere. His friends laughed and said, "Why do you think they're called weekly options?" He honed his skills through constant failures to become the Er Dai everyone sees now. He's just a post-00s who succeeded through his own hard work and talent. He couldn't help but want to share his trades. He thought if he could succeed, others could also learn from his summaries and succeed. The other is my friend Brother Kun. He is a very young and talented person. He's also just a post-00s who wants to provide a bit of free help to friends in need in the community. This is my understanding and the process of getting to know these two friends; there is no false information. Attached picture.
