For procurement engineers, the examination country does not clearly stipulate that they must undergo compulsory training before taking the examination. However, at present, except for Beijing, which does not support online registration, provincial offices do not accept individual registration, which means that they cannot apply for it themselves. Therefore, more than 90% of local institutions are registered after training. If you are an assistant, there will be more than 200 registrations, ranging from training 1000-2000. I can't help it, sometimes.
