After the rally, the K-line body clearly narrows, with frequent appearances of upper shadows. Each rebound is quickly suppressed, and the bullish momentum has significantly weakened.

The large-scale bearish pattern remains unchanged. Rebounds are still opportunities to follow the trend and short. The 68,000 level remains a strong short-term resistance, with key support zones at 66,800-66,200 below. In terms of operation, continue to prioritize high short positions and supplement with low long positions. When rebounding to resistance levels, decisively establish short positions and avoid being fooled by small rebounds.

Trading suggestion: Short around 67,800-68,400, targeting 66,200-65,600. If it breaks below 64,500, adjust your defense based on your position.
