Which big hospital in Zhengzhou recruits nurses?

Nurses must work for a period of time before they can take the nurse qualification certificate, and only after passing the exam will they be required. At first, I could only be a doctor's guide. Let's go to the hospital more often, not too big, and pay attention to the hospital environment. If it is not clean, don't go. Nurses do personal work and have the most contact with the source of the disease. If the security environment is not in place, problems will arise. After all, I don't go to the hospital occasionally. Be careful.
