From a four-hour perspective, the MA144 and MA169 moving averages are forming strong resistance, and the price continues to be pressured below the moving averages. The MACD indicator is in a bearish zone, showing only a slight rebound signal; the KDJ indicator is at a low level and has not yet shown a golden cross or trend reversal signs.

The 85,000 support level is in jeopardy, and combined with macroeconomic and industry bearish signals, the short-term downside risk has significantly increased.

Trading suggestions (for reference only, strictly set stop-loss): Recommend short positions around 87,200 and 88,200, with targets at 86,000 and 84,300.
