Today I saw a rental dispute, and it’s really outrageous.

A person renting in Jiangsu signed a one-year contract, and has only lived there for 4 months.
They were living well, but suddenly the landlord wants to kick them out.
What’s even more ridiculous is that he not only wants the tenant to move out, but also refuses to refund the deposit, and doesn’t want to pay any compensation.
He even threatened that if they continue to stay, it’s considered occupying his property, and he will sue.
The problem is, both parties clearly signed a contract.
The tenant’s idea is simple: if you want me to move out early, fine.
Then follow the contract—refund the deposit when due, pay compensation if applicable.
You can’t just say you don’t want to rent anymore and make me bear the losses myself.
Yesterday, the landlord called the police twice, and the police came twice as well.
But fundamentally, this is a lease contract dispute, not a tenant occupying the property without cause.
What’s most disgusting now is that the landlord isn’t following proper legal procedures, but is trying to manipulate the situation psychologically, pushing the tenant to leave.
He wants to reclaim the property early but doesn’t want to bear the breach of contract costs.
This is exactly the kind of person renters fear most.
When signing the contract, everything seems fine, but once he changes his mind, he starts calling the police, suing, threatening—using these tactics to pressure the tenant.
Ultimately, the tenant isn’t unwilling to move out.
They just don’t want to be unfairly bullied.
When facing such a heartless landlord, how should one legally defend their rights?
