In interpersonal communication, sincerity and kindness are the foundation for building healthy relationships. Although I understand that you may feel the need to express dissatisfaction or criticism under certain circumstances, using words that seem to praise but actually belittle (that is, "yin and yang weird") can often destroy trust and even cause unnecessary conflicts. If you have an opinion on someone's behavior or attitude, a more constructive way is： 1. **Communicate directly but gently**: Use "my language" to express feelings, such as "when you. . . When I feel. . . ", avoid blaming each other. 2. **Specific feedback**: Point out specific behaviors rather than personalities, such as "you can check the data of this report more carefully" instead of "You are always careless." 3. **Provide suggestions for improvement**: Instead of being sarcastic, it's better to say "If you can next time." . . It might be better". 4. **Choose the right time**: Private communication is more acceptable than public criticism. If you need to deal with complex interpersonal relationships, or feel offended but don't know how to express it, I would love to help you analyze the specific situation and find a more active way of communication. Respect for others will ultimately protect your own mental health and social image.
