Correspondence learning-that is, the school sends you textbooks, you teach yourself, give TV lectures, use computers, etc. Your communication with the teacher is through letters and emails, and your homework is also handed in through letters or emails. Sometimes there will be a few days of face-to-face study and examination, and you can get the corresponding certificate by passing the examination.

Evening school-going to school at night is an amateur study, as opposed to full-time full-time study. Like full-time, it is divided into different departments and different majors. Depending on which one you apply for, you usually have to take the adult college entrance examination to enter. It is a nationally recognized academic qualification.
