1, there is no camping equipment for rent on the ancient road, so tents and sleeping bags need to be brought by yourself. Personal belongings must be carried with you. You don't need a quilt, just a sleeping bag.
2. For the route, the ancient road has signposts and there are many donkey friends. Don't worry too much.
It will be summer in East China in May. Mosquitoes are more or less common in mountainous areas. Long sleeve underwear. Sun protection and mosquito prevention are essential items.
4. The danger basically does not exist. First of all, places that can be used as mass lines are developed. Huizhou route is an outdoor route, with groups of donkey friends, led by outdoor tour leaders and local tour guides. Arrange time according to actual physical strength. There is basically no danger in walking without looking at the scenery and climbing mountains. You need to grasp it yourself.
I personally don't recommend camping. The equipment is heavy and there are concerns. It is more appropriate to travel light and simply.
You can ask questions if you don't understand. I wish you a safe and pleasant journey! Hope to adopt, thank you!
