must emphasize that white water rafting is a high-risk activity and wearing a life jacket (and other appropriate safety equipment) is a basic prerequisite for ensuring safety. Without a life jacket, the risk of accidents, injuries, or even death is greatly increased. Therefore, I cannot provide any advice to attempt white water rafting without a life jacket. If you plan to go white water rafting, it is recommended to follow the following safety guidelines: 1. Always wear a certified life jacket and other necessary protective equipment. 2. Participate in professional rafting activities led by experienced guides and listen carefully to safety training before the activity. 3. Check all equipment to ensure that it is in good condition. 4. Pay attention to changes in weather, water currents and environment, and avoid activities in adverse conditions. Please remember that safety always comes first. Any attempt to compromise safety standards in extreme sports may result in serious consequences. For the safety of you and others, please be sure to take all necessary safety measures.
