When was the Third Affiliated Hospital of Zhangjiakou renamed Jianguo Hospital?

Well, if the people above don't know, don't talk nonsense. The Third Hospital and Maternal and Child Health Care have been merged and called the Third Maternal and Child Health Hospital. The Third Affiliated Hospital was originally a Zhangjiakou regional hospital. Later, the city merged and gave the name Jianguo Hospital. The hospital was not satisfied with this name and cooperated with Hebei North College. However, there is not much contact with the school, the First Affiliated Hospital and the Second Affiliated Hospital. The name of the Third Affiliated Hospital has not been recognized by the city, so the official activity is called Jianguo Hospital and the daily work is called the Third Affiliated Hospital.
