Most of the college students are living away from home for the first time. So the most important thing is to learn how to manage their finances carefully. As a college student, one must plan his budget (预算) well on a monthly basis. For example, suppose one's parents give him an allowance of 800 yuan each month, 50% of that should be set aside for food because food is expensive here. Then one should keep 10% for transport, since sometimes he may need to take a taxi to go to places. Books and magazines will account for another 10%. Finally, one should set aside about 10% for entertainment. It's true that college students are there to study, but all work and no play is not the proper way to study. After all these expenses (花费), you will be left with 160 yuan for a rainy day.
