Tattoos have a good prospect, so there are not only many people studying, but also many training schools. But many people don't know how to choose a school when learning tattoos. The following is a brief introduction to several aspects that need to be considered when choosing a school: 1. Understand the teacher's tattoo works and students' practice works, and you can see the aesthetics of the works and the coloring effect and lines of the works. This reflects the technical level and teaching level of school teachers. 2. Understand students' feedback, which is the real situation of students' learning and can reflect the teaching situation of the school. We should not only look at the students' evaluation online, but also go to the school to see the students' class situation, seriousness and learning atmosphere. 3. Opportunities for real people to practice in schools. Practice is very important for tattoo beginners, because it is an important link to transform theoretical knowledge into practical experience, and it is also a prerequisite for employment.
