People who temporarily lack economic conditions for psychological counseling can call when they need to communicate; Calling the hotline is very stressful for many people, probably because they are worried that the other party will understand and treat themselves well, respect themselves, be ignored or discriminated against, and so on.

The improvements and inventions of telephone in history include: toner microphone, manual switchboard, program-controlled telephone exchange, dual-tone multi-frequency dialing, voice digital sampling and so on.

New technologies in recent years include ISDN, DSL, analog mobile phone and digital mobile phone. Telephone industry is usually divided into telephone equipment manufacturers and telephone network operators. Historically, network operators usually have a national monopoly position. With the opening and integration of the global telecommunications market and the development of technology, there has been a situation in which many operators compete in the same market.
