Highschools generally DO NOT disclose the number of students they accept by nationality, let alone the top ten boarding schools as they guard their admission numbers closely. Generally the various schools will consider accepting no more than 2 or 3 students from China each year but you should not consider that as the rule.
翻译：高中一般不会发放关於国藉和收生率的数据。前十的学校对於自已的数据会保护得更紧。一般来说，不同的学校每年不会收多於两个或三个大陆学生，但你不需要看成是「铁的规矩」。
