没完没了 (méi wán méi liǎo): 끝없이

The renovation noise from upstairs went on and on from morning till night, making it impossible for me to concentrate on my work.

The rain has been falling endlessly for three days, and the streets are flooded.

My mother endlessly reminded me to wear more clothes; it was a bit annoying, but I knew she cared about me.

The meeting dragged on endlessly; everyone was exhausted, but no one dared to suggest a break.

He always talks endlessly; once he starts, he can't stop, often wasting everyone's time.
