There is a computer school called Beijie Computer Training College on the fourth floor of Xicheng Building, which is about 20 meters opposite to Zhangjiagang Traditional Chinese Medicine Hospital. One of my colleagues studied there before, and they all said that the teachers there were meticulous and patient, and they all practiced after learning. What they learned that day can be consolidated and mastered, and you can go to the field to learn it yourself. You can ask me again if you don't understand.
