I want to learn wedding photography myself, but I don't know how to learn it there.

Find a photo studio with a good reputation as an apprentice, be smart and diligent, and you will always learn. Don't just learn technology, but also learn other people's business ideas and methods. If you do well, you must have your own unique management method. Gradually accumulate experience, and one day you will have your own photo studio. Good luck and early success.
