During the Spring Festival, the yield peaked at 680%. It's been a roller coaster ride these past two months 😂. Selling Changfei Fiber and moving to SK Hynix resulted in huge losses, but I still added 30,000 HKD at the bottom of the 2x long SK Hynix position and made a slight profit. In recent days, I received a medal on Tonghuashun for A-shares, commemorating the experience. The stock market is vast and boundless, so I'll keep working hard.
