"Every worker coming to Beijing has their own reasons．No one lives here without a dream，"said Chen Jianguo，a 35﹣year﹣old food deliveryman（送餐员）from a small city called Songyuan．

Chen Jianguo dreamed of having his own business in Beijing about 16 years ago when he graduated from senior high school．but his father asked him to take his place as a truck driver at the oil field．Although Chen disliked the job，he didn't want to let his father down．He took the job as a truck driver． Then he got married and had a son．

"I got quite good pay， but life was boring there during those years． Most of the time I had nothing to do， because the trucks were not often used，"said Chen．

Two months ago， Chen decided to give up his job and come to Beijing． His wife agreed that he should go for his dream．

Chen has been a food deliveryman for a month． He works 15 hours every day and hardly has time for lunch at noon． Chen spends only 10 yuan on each meal to cut the cost of living in Beijing．"I want to give a better life to my wife and little son，"he said．"I must work harder and try to become the best food deliveryman at my station．"Chen likes his job because he can meet many different people．Every"thank you"from a customer is like praise for his work．

Chen plans to start his own restaurant in the future，so he always writes down what food people have ordered．In this way，he gets a better knowledge of people's tastes．
