According to the Buddhist view of cause and effect, there must be a cause for reward. Congenital ear malformation is a bad result. According to the law of causation, it may be the result of intentionally or unintentionally hurting the ears of all beings, such as tearing the ears of people or animals and cutting them off. Nowadays, when people keep dogs, they often cut off their ears, which may cause ear deformities in future generations. There is also that past lives are evil deeds. Although reincarnated, there are still unfinished reports, leaving traces of past lives.

In short, according to the view of causality, whether this life is successful or not, whether it is good or bad, it is before past lives's cause of good and evil. Know the reason, be careful what you say and do, be lucky if you do more good deeds, and die if you do more injustice.
