How to spend the least money while traveling?

If you can hitchhike on the road, hitchhike; if you can’t hitchhike, just walk. If you can live in a sofa bed at night, stay there. If you can't live in a sofa bed, sleep in your own tent. When it comes to eating, I bring a simple stove, cook some noodles with some green vegetables and peppers, catch some fish when I encounter a river, catch a rabbit when I encounter a mountain, and dry the meat if I can’t eat it. Just stand in the river and forget about it. Smile and say hello to people you meet on the road. Help whoever you can, and do what you can. Maybe someone will treat you to a meal or stay at their house for free or something. When encountering scenic spots on the road, I evade fares if I can. When I encounter ancient towns, I go in at night. When I encounter mountains, I walk in early in the morning. Ticket sales have not started yet. If you really can't escape, just forget it and don't go in. Just like this, you may not even be able to use 1,000 yuan a month. Haha, what a joke.
