As a major channel of consumption i

As a major channel of consumption information，the rating is an efficient source of information for shopping in our own consumption.Interestingly，the same rating may have different influences on different consumers. I tend to consult consumption ratings whatever I purchase.Firstly，the higher rating means the higher quality of the product，or better service.Based on the ratings，I bought my beloved backpack，saw interesting films and tasted delicious foods.Secondly，ratings can save time to make decisions in shopping.For example，there are huge numbers of reference books which I am often confused to choose from.In that case，it is both convenient and economical to buy books according to the ratings.
