it's amazing to get a story.And i think that's why i am willing to make friends with the salesmen.in some degree,they are my appreciative persons.In essence，we are the same people.in my university period,i hoped i could be a medical representative,but my parents were against me.And i  gave up.Then i tried to get a better degree.however,i failed because of some objective environment.but now i am still being on the road.And i will go further.
