Advantages: First, it is a way to simplify procedures and optimize processes. Overseas certification has been cancelled, and there is really no need for Hong Kong and Taiwan to be special. This is just following the crowd. It is understood that it takes time to apply for this study certificate, which is only needed when you first enter the workplace. After the certification, it was thrown into the personal file, and the simplified procedures have indeed made great progress. I hope everything goes well in the future. Second, education in Hong Kong, Macao and Taiwan is more in line with internationalization. Hong Kong, Macao and Taiwan follow the western education model and implement bilingual education. The content of the class is practical and can be applied to the working environment. As far as disadvantages are concerned: there is no disadvantage in the publication of this document. This further shows that Hong Kong can feel the benefits of this policy. Simplify the procedures for students from Hong Kong, Macao and Taiwan to work and live in the Mainland. The profile can also reflect a trend. Under this policy, more people may consider studying in Hong Kong, Macao and Taiwan. On the other hand, although this proof is cancelled, an alternative scheme is given. So it doesn't matter. If you need proof, you can still go through the procedures online. Of course, in real social life, sudden changes will definitely take time and energy to adapt. There is no doubt about it, and don't worry too much.
