Professionally trained volunteers in Suicide Prevention Service patiently listen to elder callers. They persevere in a service value of "Caring, Listening, Acceptance and Companionship" , they understand the feelings and problems faced by the callers and sincerely listen to their hearts without judgement and opinion. By focusing on callers’ emotions and suicidal intentions, they hope to build a platform that enables callers to express themselves, shore up their confidence in their own values and together confront callers' problems.
