In the morning session, the Shenzhen Component Index and the ChiNext Index both experienced declines exceeding 1%, marking a significant downturn in the broader market. Amidst this general weakness, the oil and gas sector stood out, defying the market trend with a notable surge. Stocks such as Tongyuan Petroleum reached their daily trading limits, highlighting the sector's strength. Additionally, the nuclear pollution prevention sector exhibited robust performance, while gold and rare earth permanent magnet concept stocks also gained ground.

Conversely, new consumer concept stocks underwent significant adjustments, with the beauty and personal care sector leading the decline. This downturn reflects a shift in investor sentiment towards these areas. Overall, the market was predominantly bearish, with over 4,400 stocks closing in the red, underscoring the broad-based nature of the sell-off.
