The early social training classes were suspended for half a year, and the quality was not guaranteed, so that employers had a bad reputation. Now they basically cooperate with schools. It's better to teach yourself and follow the code. What you can do is to write what you have done in your resume, cut some pictures and write an explanation to show your attitude, which is more useful than simple training experience. If amateurs really need training, it is recommended to find training for half a year.
