The recent hot topic is Trump's visit to China.

We won't jump on this trending topic here, just get straight to the main point about today's market:
The speed of decline is matched by the speed of rebound.
I've said that as long as 78,000 isn't broken, the bulls will always make a comeback.
The daily chart's major trend remains firmly bullish,
The previous correction and shakeout are basically over,
All moving averages are supporting the price upward,
The bearish momentum is quickly fading,
Overall, the upward trend has resumed,
Next, 82,500 is the biggest resistance overhead,
Below, support is at 80,000—don't panic as long as it holds.
The 4-hour rebound momentum is very strong,
The lows are gradually being raised,
The bulls are regaining control of the market,
As long as support at 80,000 holds,
This rebound can continue to push higher.
But also watch out for too much enthusiasm;
The upside space is limited.
The 1-hour short-term upward trend is ongoing,
But indicators are a bit overbought,
Reaching around 81,500 may encounter resistance and pull back,
Don't chase high out of excitement.
Focus on key resistance at 82,000-82,500,
Support levels at 80,500-80,000,
You can consider small positions on dips for low buy-ins,
Be cautious when going long near resistance levels,
Near resistance, consider staggered entries for short positions,
Set stop-losses properly to secure gains.
