Renew X2 visa in China

Hi, I came in January to start a Chinese course on February in a university. Covid started to spread in January, so the course was cancelled. I didn't go to class, but I kept my X2 visa because of the situation. Now I would like to get private classes, so I need to go to a training center and for that I need another X2 visa, because mine is going to expire soon. Is it possible to get the visa from a training center inside China's territory? I've heard nationality has to do with this matter. I was born in Spain.
