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.

　　Itend 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 amounts 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.

　　There is no doubt that it is unwise to depend completely on the ratings in consumption. The advantages and disadvantages of ratings are often closely related. It is necessary to hold an objective attitude towards ratings.
