樓下的賤婆租人地間房教琴，怎麼辦?

首先我唔明白你說的房屋署,即你是住公屋 ? 如果系公屋應該唔可以租給別人住,房署會有權收翻單位, 你可直接去舉報佢, 咁就可以搞店了.

第二, 你有冇經管理處親身同你樓下相討,因為你樓下可以裝修間房做隔音設備,例如加吸音棉,厚地絨,關窗等,不過記得一定要有管理員在場,如果對方唔肯做, 咁你就可以同佢一拍兩散, 佢上堂時你在樓上大力打波,等佢上唔到堂, 學生自然走, 夜晚又九唔九又打波, 等佢受翻, 直至佢肯改為止.

重有你要同佢講, 你唔會阻佢揾食, 但佢都唔可以阻你温書, 如果佢都唔改,你會用24小時噪音管制條列來報警告佢.

have a nice talk with her,dont make any hitting action,try to complain to other departments or seek help form lawyers and professional advice,they may help you^^
