First of all, you must change the dormitory, if it is near (such as next door, across the hall, or Jiang 'an's big dormitory), and someone is willing to change with you, be careful that both parties are willing, and both bedrooms are willing. You can secretly change it yourself, nobody cares.

Secondly, if you change the distance, you must get the consent of the tour guide. Otherwise, he will be unhappy when he knows.

Finally, it is generally because the dormitory is not harmonious that the dormitory is changed. . . . . . I suggest to consult with the instructor or help the class cadres solve the relationship. There is really no way to change it.
