It is a very one-sided and inaccurate stereotype to generalize Northeastern people as having strong personalities and prone to disputes. Northeastern people are warm and generous, value friendship and loyalty, and are often proactive and responsible in teamwork. In a team, promoting good cooperation can start from the following aspects: 1. **Strengthen communication and understanding**: Encourage members to communicate frankly, enhance understanding of each other's cultural background, personality characteristics, etc., eliminate misunderstandings, and treat individual differences with an inclusive attitude. 2. **Create a harmonious atmosphere**: Advocate a positive, friendly, and respectful team culture, organize more team building activities, and enhance member feelings and cohesion. 3. **Clear goals and rules**: Jointly formulate clear team goals and clear work rules and processes, so that everyone knows the direction and requirements clearly, and reduce conflicts caused by unclear responsibilities. 4. **Cultivate emotional management skills**: Through training, sharing, etc., improve members' ability to perceive and manage their own emotions, and respond calmly and rationally when encountering problems. 5. **Make full use of complementary advantages**: Fully recognize the advantages and expertise of each member, reasonably allocate tasks, let everyone shine in their respective areas of expertise, and enhance the sense of achievement and motivation for collaboration. We should not try to "ease" the so-called personality based on wrong stereotypes, but should build a positive and efficient team cooperation environment based on full respect and acceptance of real and diverse individuals.
