After yesterday's decline, it is recommended to reduce positions. The rebound at 109000 has just reduced positions to 106800. Now, during the rebound at 108500, add some points.

Finally, I have resolved my 108,000 short position and reduced my holdings by half, let's see if it can go down further. The drop is a bit severe. Of course, there is a possibility of a small rebound to 109,000 for a short position. Sooner or later, it will drop to 100,000. This year, it must go down to 90,000 or even below 70,000, it's just a matter of time to see if you can hold on. I only play long-term; for short-term, if I make a profit, I just run.
