Hello; There are many such training institutions, and the training contents are almost all domestic simulation systems (teaching systems). The training content in China is also very simple and the training time is very short. However, after the training, if employment is involved, students can only operate domestic ticketing, and the error rate will be there. If the real system (settlement system) is used, the cost is high, but for students; This is very beneficial, because they have not only learned the domestic content, but also involved the international content, so the future employment will be broader than that in China and the starting point will be higher. It is understood that there are very few drums that can really be trained by the system at present, such as Zhong Yi Shenzhou, which is a mature institution that has been in operation for many years, but their requirements are higher, and they are all aimed at airlines, not ticketing companies, and generally only students trained by domestic systems. I hope I can help you! Some purely personal advice.
