  The Japanese pay much attention to the luck of telephone numbers.

The bathhouses,for example,like to use 4626,because when read in Japanese,it has the same pronunciation (發(fā)音) as "have a good bath". Both the clothes shops and the butcher's like 4129 better than any other numbers because this number can either be read as " good dress" or " good meat".

  Since these numbers are connected with something nice,people can remember them very easily. So they have become advertisements for the shops.

  On the other hand,there are also telephone numbers which are regarded as forbidden (被禁止) by the Japanese people. 1564,for example,has the sound of " kill people" while the number 4219 has the sound of "people die".

  At present,there are about 44 million telephones in Japan,yet it is almost impossible for everyone to get a lucky telephone number. So these numbers have become commodities (商品) and can be sold as goods. The price can reach as expensive as 222,000 Japanese yen (曰元) .
