I'm really convinced. I emphasized the importance of 78,500, but as it approached, I still kept greedily holding on, and the result was a hit. The market here bounced again, and last night launched another upward attack, with the high point reaching 81,999 to resist and then start to pull back. There is a possibility of further correction in the short term. Whether it can fall deeply is still unknown. Currently, at the price of 81,000, go short directly, with a stop loss at 81,400.
