By default, praise is equal to no score, and by default, I won't give you something as good as 5 stars.
However, the score is based on the average number of people, and no evaluation will not affect the score.
In order to improve the existing score, we can only try our best to get as many customers as possible to score 5 points.
In addition, this score is only accumulated for half a year (or one year), even if no one scores it continuously, it will change.
