I am about to move to Hong Kong and already decided where I would like to stay. But now I was wondering if it is necessary to specify the length/period of the lease/rental. In Germany, you usually rent an apartment without specifying the lease period. You just have to cancel the agreement three months in advance when you would like to move to another place. Is there a similar rule in Hong Kong? I am not sure if I will stay in Hong Kong for 18 months, 24 months, 36 months... so it would be great for me to have an unspecified lease period.
