Currently, although there is some rebound, it is still below the middle track and overall weak, with limited rebound strength. The Bollinger Bands are opening downwards, the middle track continues to weaken, there is significant pressure above, and the trend is bearish. The K-line is oscillating at a relatively low level and has not formed an effective reversal signal. It is highly likely to continue the downward trend, and one can place short positions based on key resistance levels, with stop losses set above the resistance level.

Looking at the four-hour chart, there is support at the previous low points, but no effective reversal has occurred. If the current rebound is blocked by the middle track or key pressure levels from the previous downtrend, it is very likely to fall back.
