Can two property companies be entrusted with the management of the property community developed by stages? Why?

If it is the same community and there is no closed wall, it cannot be managed by two property companies. In the past, this phenomenon existed. There is a man named multi-head management, and the two companies buck-passing each other. Developers should be responsible for this matter. Property management regulations clearly stipulate that this kind of thing cannot be allowed to happen again, and local property management government departments must ban this practice of developers.
