There are two content types of Regions and Cities, each region includes cities and each city includes a region, how to make it so that when a city is added to a region, a region is automatically entered and vice versa?

    I was helped by this module Corresponding Entity References , for robots you need to do the following steps:

    1. Create the appropriate content types.
    2. Create reference fields for each type.
    3. We include the module and configure it here: Configuration >> System >> Corresponding entity references

    Tried to use the Corresponding node references , but in my case it did not work.
