Personally, I think it's good to attach an internship, but attaching two tubes is too strict and rigid. Of course, the overall strength of Annex I is better, and the orthopedic and children's hospitals attached to Annex II are obviously better than Annex I, because it was originally attached to Annex I, and now it has become an independent hospital. If you work, the management in Annex II is stricter, and the salary seems to be a little higher than that in Annex I..
