I've decide to take these six items:the sleeping bag,the mobile phone,the flashlight,the lighter,compressed biscuits,an appropriate.
one,When camping in the wild, a comfortable sleeping bag can indeed bring warmth and peace to one's heart. 
two, a mobile phone can help us navigate in the wilderness.  in case of an emergency, I can use the mobile phone to call for help and contact rescue personnel.
three,A flashlight can be used for illumination, sending distress signals, and deterring wild animals.
four,A lighter can provide me with a fire source in the wild, allowing me to keep warm and heat my food.
five,Compressed biscuits can quickly replenish my energy when I'm hungry, and they're compact and extremely convenient to carry.
last,An appropriate weapon can save my life in an emergency.
