A mobile phone nickname refers to the mobile phone number used for communication. The number usually consists of 11 digits. When it is arranged regularly, smoothly or repeatedly, it is called a nickname. It also includes the auspicious number custom, and the meaningful appearance and frequency can also be called the beautiful number.

In China, some numbers are popular, such as "8", "6" and "9". Among them, "8" is considered as an auspicious number, because its pronunciation is similar to words such as "making a fortune" and "making a fortune"; "6" is considered as a symbol of smoothness and satisfaction; "9" is considered as a symbol of longevity. Therefore, the combination of these numbers in the mobile phone number is considered to be a beautiful number.

In addition, some meaningful and memorable number combinations, such as serial numbers and repeated numbers, are also considered as pretty numbers. Nicknames are usually popular and expensive, and some people will pay a lot of money to buy their favorite nicknames. However, there is no difference between the beautiful number and the ordinary mobile phone number in use.
