Thanks
I'll print every document out. My tenancy agreement, the eviction emails of the landlord's employee, his message saying that he would break the door if I changed the locks, and the plane tickets of my brother if he exhibits "proofs" saying I let someone else sleep at the apartment.
My only fear is that the landlord might have a solicitor representing him, and I'm not one, so I'll have to defend myself in English, translated in Cantonese, that's going to be folkloric.
My line of defence will be that I put the flat on Airbnb to check if I could rent it out, and if I indeed have had a rental proposal, I would of course have asked permission to the landlord in order not to break the tenancy agreement.
