Safety and preparation are very important when going on a zipline adventure without professional guidance. Here are some things to note: 1. **Choose a suitable location**: Make sure to choose a certified and well-maintained zipline site, and avoid trying ziplining in unknown or uncertified locations. 2. **Check the equipment**: Carefully check the zipline equipment, such as safety belts, pulleys, gloves and helmets, to ensure that they are intact and meet safety standards. 3. **Understand the instructions**: Before ziplining, carefully read and understand the instructions for all equipment, including how to wear a safety belt, how to use pulleys, etc. 4. **Pay attention to weather conditions**: Pay attention to weather forecasts and avoid ziplining in windy, rainy or thundery weather. 5. **Health assessment**: Make sure your physical condition is suitable for this activity, and avoid health conditions such as heart disease, high blood pressure, etc. that are not suitable for high-intensity activities. 6. **Wear appropriate clothing**: Wear comfortable and suitable sportswear and shoes, and avoid wearing loose clothing or accessories to avoid getting stuck while zipping. 7. **Stay calm and focused**: Stay calm during the zipline, pay attention to your surroundings and safe operation, and avoid accidents due to tension or distraction. 8. **Follow the operating procedures**: Follow all safe operating procedures before, during and when landing, and do not try risky actions. 9. **Confirm safe landing**: Make sure someone is responsible for confirming safety at the landing point to avoid accidents caused by inattention. 10. **Travel with friends**: Try to explore with friends or family, do not zipline alone, and make sure there are others who can help. Most importantly, in order to ensure your own safety, try to choose a guided and experienced organization for high-altitude zipline activities.
