Thank you for your question. The consideration of regional cultural differences in team building is an interesting topic. Although some northeast people have a straightforward and cheerful personality, we should avoid using regional stereotypes to design team strategies. Everyone is a unique individual, and their personality characteristics are affected by many factors, not just geography. Effective team building should: -Focus on individual characteristics rather than geographical labels -Create an inclusive and respectful environment -Encourage open communication -Design a variety of team activities to meet different personality preferences The most important thing is to understand the actual characteristics and needs of each team member, rather than adjusting strategies based on geographical assumptions.
