To implement the instructions made by General Secretary Xi Jinping and the CPC Central Committee on epidemic prevention and control to strengthen psychological intervention and counselling, and to make targeted humanistic care a priority, the Youth Rights Protection Department of the Communist Youth League of China immediately coordinated the deployment of the Special Action 12355 Psychological Assistance for Young People. Since the launch of the campaign, more than 10,000 times of consultation have been received and answered. Apart from problems related to epidemic prevention and control, interpersonal relationship, study pressure and psychological confusion also account for a large proportion. Psychological counsellors connected via 12355 from all over the country provide professional mental health and crisis intervention services to help young people and their parents scientifically understand and cope with the epidemic and reduce psychological interference and possible psychological harm. This book collects the common and typical cases from the 12355 network platform of the Communist Youth League of China and the 12355 youth service desk in some provinces and cities, which are used as the reading materials for professionals, teenagers and the parents.
