There are many training institutions of various natures. The suggestion is to find a training institution with training qualifications, or a large brand company with training qualifications, which can also provide employment opportunities after the training.

In addition to knowing whether the training institutions are qualified, we should also examine whether the certificates issued by the training institutions are recognized by the state, whether they are authoritative, whether the teaching environment meets the requirements and whether there are relevant training equipment.

Finally, whether the training institutions can provide free audition opportunities can only be better chosen and judged after on-the-spot investigation and audition.
