Climbing without a safety rope increases the risk, but you can take the following steps to reduce the risk: 1. **Choose a suitable climbing site**: Choose a climbing site with moderate difficulty and good road conditions, and avoid high-risk areas such as decayed rocks or loose gravel. 2. **Master climbing skills**: Improve your climbing skills and physical fitness, including grip, stepping and body balance, to enhance your climbing ability. 3. **Warm up and prepare for safety**: Warm up thoroughly before climbing to prevent muscle strain. At the same time, you should check your climbing equipment to make sure everything is in good condition. 4. **Climb with a partner**: Try to climb with others so that you can help and support each other when you encounter difficulties. 5. **Study the route**: Before climbing, carefully study the climbing route to understand each key point and possible dangers in order to develop a response strategy. 6. **Stay focused**: Stay focused while climbing and avoid distractions, especially in difficult or dangerous places. 7. **Learn the falling technique**: Master the correct falling technique to reduce the possible damage caused by falling. 8. **Regular training**: Carry out regular training to improve strength, flexibility and endurance to better cope with various situations in rock climbing. Despite taking the above measures, there is still a high risk of not using a safety rope, so be sure to carefully assess your ability and environmental conditions.
