How to travelling with no money ?

One of my friend share a travelling story with me, I feel so moved, so I want to write it here.

My friend John is very love to travelling all around China , last year during Chinese New Year holiday , he take his wife, his 5 years old son to travelling to Xi An city . On the way to Xi an road, he met one university student Peter , Peter is very polite, he show his students card to John, He explain that he is travelling too. Now he want to back Xi an university school, he want to be John’s car. John agree and take the student together . they have nice chatting all the time, to share all travelling story , beautify scene etc. . After around 5 hours by car, they are arriving to Xi An city finally. They all feel so happy.

When they are going to departure, Peter said : “ I want to offer dinner with your whole family , even if I don’t have too much money , but just simple food. I hope it is ok for you” .John feel so surprised . They enjoy steamed stuffed bun together.

John told Peter, why you want to offer us dinner , in fact I don’t mind about this. I know you are a student and don’t have money at this moment. 

Peter share his special travelling story with them. During one time his travelling to Hainan, he met one guy , the guy give him lots of help and they have nice travelling together. But when they are going to departure, the guy ask Peter to offer him a dinner. Peter feel so surprised and unhappy , because he is not so much money . But he can not refuse, so he used up all his money to offer that guy fancy dinner . after the dinner, the guy told Peter, I heard lots of interesting travelling story about you , I always heard that you get lots of help from other people , but I never heard that you offer any help to anybody . that’s not very good. Even if we travelling with no money , but we can not only get other people’s help , we also need to learn help others .that’s very important.Peter always remember this and he want to do what he can do to help others during his travelling.
