In my country, there are a lot of superstitions. For example, if you hit a black cat when you are driving, that means you will be very unlucky the whole day.
People are very mindful of numbers in my country.The number "4" has the same pronunciation as "die" so "4" is usually unlucky. Some people don't like to use number "4" in their phone number or car number. On the other hand, numbers "6"and "8" indicate success and getting rich. This means you do everything very well.
