First of all, Qingdao Fangte does not have any official group purchase! There is no student policy directly (student ID card is not favorable). The group purchase you reported should be a student group that Fangte gave to the travel agency!
In this case, just check the travel agency! Because students are with the group, there are many people! Generally, only the photo of the certificate is consistent with mine! Of course, if the age difference is too big, it won't work!
