最基本的物质需求得到满足之后，唯一能够不断增加个人幸福感的事情就是帮助他人

International Direct Dialling (IDD) is an international telephone call dialled by the caller rather than going via an operator. The term International Subscriber Dialling (ISD) was used in the United Kingdom and Australia until the terminology was changed to International Direct Dialling. Since late in the 20th century, most international calls are direct dialed.

打国际电话不通过接线员，20世纪最后，大多数国际电话都变为直拨。

International calls are made by dialling the international call prefix for the country one is in, followed by the country calling code for the country one wishes to call, then the phone number within that country. When phone numbers are published for use abroad, they typically include the country calling code, but replace the international call prefix with "+" to signify that the caller should use the prefix appropriate for their country.
