　　What is shown in the table above indicates that dramatic changes have taken place in the daily expenses in Xi'an from 1995 to 1999.The expenses on food have declined by 30%while those on clothing and recreation have increased respectively by 9%and 7%.
　　There are two factors accounting for these changes.In the first place,the risen income resulting from economic growth plays a vital role in the less expense on food.In the second place,when food presents no worry to the average,people begin to focus more of their interest on handsome appearance and happy leisure time.As a result of such a shift,spending on clothing and recreation increases year by year.
　　From the analyses made above,with the further growth in economy and more changes in life style,the tendency indicated in the table will continue in the better direction.
