These are much associated with spiritual people, which means they have the better learning about it. The younger generation doesn't believe on acts that doesn't have the proof. These are well connected with cultural and traditional activity. Many follow it for a reason, but when it comes to gambling whatever you follow you're luck decides the outcome.
...Many region have different cultural beliefs. and they are not the weak one.

Every area that has that culture will continue to carry out its culture because it is a tradition in their place of residence. But maybe the younger generation who don't want to be involved in that culture will leave it because they think it doesn't make sense.
