1, whether you buy an encryption lock or not, you can attend a free training class.
2. Just bring a pen and paper when training, preferably a USB flash drive, and you can bring courseware or something.
During the training, the lecturer said that everyone has a computer, and you can operate it yourself below. The lecturer speaks a little and gives time to practice.
If you want to sign up, you can go to Guanglianda Shinkansen to sign up, as said upstairs, or you can call their customer service directly and ask them to sign up for you. You can sign up for any software training you want. I'll call you when the class starts. Software for pricing, reinforcement and graphics is generally available every month.
