Yesterday's rebound made the downward momentum slow down a bit, but the overall monthly and weekly chart patterns still remain weak. Continue to maintain a cautious attitude about the bottom and focus on short-term trading.

Resistance is around 80,500; the first touch can be seen as a potential move down, while support is around 76,300; the first touch can be seen as a potential move up. Remember, the first touch is the best opportunity, the second touch is usually an average opportunity, and the third touch is a chance to escape.
