Where prejudices lead?
In the countries of the southeast, excessive superstition leads to unimaginable confusion, when a building of twenty floors is immediately deprived of the fourth, and fourteenth. And if, for the sake of European tourists, floor number 13 is removed from the list here, then it turns out, that from the twelfth floor you immediately get to the fifteenth.
The Chinese and Japanese practically do not mention the "four" in everyday life. Especially during moments of relaxation, during holidays, when someone from the household got sick. Also, you should not bring objects to the house in such quantities during this period..
Associating all the failures with this figure, tetraphobes are most afraid of 4 April. Considered a bad number, he was excluded from the numbering of wards in the hospital long ago, house designations, places in restaurants, phone numbers.
In Japan and China, superstitious fears are still alive and well, even in business..
Selling real estate with this number or real estate in a place with the same name is almost impossible. And if you put someone close to hospital ward No. 14, # 24 or # 42 is an insult for the rest of your life..
Japanese understands without explanation, why do you need to bypass the "four". No less unlucky for the Japanese is the number "9" - consonant with torment. Therefore, "49" - to be afraid like fire, drawing parallels with martyrdom.
But local omens are absolutely inappropriate for foreign business., where you really can't do without this figure. And the generated cell numbers cannot be changed at will. The rest - we will fix, throw away, similar in your own way.
One example - Nokia never used the number "four" for its models, produced for Asian consumers.
