How to evaluate it varies from person to person, and tell the truth. If you strictly follow the requirements of any training, you will definitely make progress if you stick to it. The quality of training depends on what you want to learn, the cost performance and training price of what you have learned, and the amount of training water (more or less water to promote training). Yu Zhenhua's ui training will be lower than that of institutions, but it is also relatively unsuitable for newcomers. It is recommended to have a certain foundation before signing up for study. If economic conditions permit, we can really avoid detours through training and study, but training is only a small part. It is important to apply what you have learned to practice, not just training.
