I recently heard that I couldn't get a visa to Spain. Does anyone know the details?

You don't need to make an appointment, but it seems that the maximum number of applicants per day in Shanghai Spanish Visa Application Center is 140. In order to ensure that your visa application can be accepted, please make an appointment online and then come to the center to submit your application, and make sure to make an appointment at least 15 minutes in advance. There is no such notice in Beijing and Guangzhou at present.
