How many times are there * * * ratings for four-star hotels?

Four-star hotels were rated twice at a time. Hotel star rating is divided into three stages, namely, initial rating, re-rating and confirmation rating. The initial evaluation and re-evaluation are necessary, and the confirmation evaluation is the final evaluation and identification of hotels that have passed the re-evaluation. Therefore, a four-star hotel needs to be evaluated twice, that is, the initial evaluation and the re-evaluation.
