In our daily life, it is very important for everyone to recognize and understand ourselves and other people’s emotions correctly, and to manage and regulate these emotions properly. Thus, emotional competence has great significance for everyone’s development of metal health and physical heath. Children’s emotional competence means that children have emotional knowledge, emotional regulation and expression skills, and the ability to recognize and understand their own and others’ emotions. Children’s emotional competence plays an important role in improving their cognitive abilities, including attention and language competence. Children’s emotional competence can also increase the level of children’s mental and physical health, and improve the ability of children’s social interaction. Furthermore, children’s emotional competence can help children reduce their risk behaviors, such as smoking, alcohol abuse, aggressive behaviors and addictive behaviors. The two programs of Teaching Pyramid and Promoting Alternative Thinking Strategies have the same goals which are in order to improve children’s social-emotional competence and decrease their emotional and behavioral problems. In order to improve children's coping skills under stressful situations, the researchers developed a Fun Friends Project. In this project, children, families, teachers and schools are all involved in the process of intervention. In China, Kou Yu et al. (2006) developed a comprehensive intervention project to enhance children’s emotional competence. In addition, the Ministry of Education and China Association for Science and technology developed the science education experiment ‘Learning by Doing’ which also contributed the development of children’s emotional competence. Therefore, from the perspectives of improving the outside environment and increasing their abilities, these projects effectively decreased children’s emotional and behavioral problems, improved their abilities of emotional recognition, emotional management and emotional regulation. Currently, the topic of children’s emotional competence had drawn great attentions by some researchers. However, there are still many issues to be explored further in this field. Researches in the future are suggested to explore the influencing factors and mechanism of children’s emotional competence, prepare special questionnaires and perfect its interventions. In a word, emotional competence is an issue of individual life-span development, and it is very important for children’s growth and development, in the future, the majority of researchers should continue to explore and study children’s emotional competence more deeply.
