There is no ranking. In Xi 'an, there are Huayi Times, Bona and Boyi who have scale and qualifications. The teaching quality and service in Huayi era are excellent; Bona is an old school with acceptable teaching quality; Boyi is a flashy institution. Others, such as Lanyi, Jinkoucai Foreign Hospital, etc. Either there is no education or there is something wrong with the teaching atmosphere.
