Water from the toilet tank gets to the hair

This is the last time you pressed the water for too long, resulting in the plug not reset, you can press it again, just hear the snap sound to reset.

It should be that the gasket is broken, just go to the place where the toilet is sold and buy one and replace it.

It is caused by the high level of the flush toilet and the low level of the tap water.

The water in the toilet tank is not drinkable, it is tap water, and generally no one cleans it, it is not very clean.

I really don't know why it leaks, so I need to find a professional to fix the leaking toilet tank, is there any other way?
