As I said a several times before, communist labour unions are very powerful in India. Most of them are backed by the communist parties who have CCP patronage.
If by CCP you mean the Chinese Communist Party, that's bullshit propaganda. But it is true that they used to enjoy the patronage from the former USSR with whom India did have a friendly relationship.
If someone has two (or more) houses that are declared as self-occupied (maybe empty or in use, but not let out) then that person can treat one as where the person stays and the other(s) is treated as rented. This applies across India as this is part of the income tax rules.
