Is knocking on the iron basin an invitation to ghosts?

Knocking on the iron basin is superstitious and can't attract ghosts.

Ghost is a superstition, which refers to a supernatural phenomenon, that is, the soul still exists after death. In science, ghosts have not been proved to exist, so knocking on iron pots can't attract ghosts.

On the contrary, knocking on the iron basin may be considered as a kind of noise, which may affect people's sleep and rest. In addition, knocking on the iron basin may also be regarded as an uncivilized behavior, which may have an impact on people's social image and reputation. Therefore, we should respect science, not believe in ghosts, and abide by social morality and laws and regulations.
