My daughter is 4 years old. She is especially fond of gossip and thinking. For example, when she is alone, she talks to herself about what's at home.

Personally, this may be because your daughter didn't communicate with you normally, and you usually don't care enough about her. You can try. Usually when he plays alone, he sits beside her, spends more time with her and tells her what to do. This will not only enhance the affection between you two, but also exercise his language ability. You can tell him some beautiful fairy tales before going to bed. It will make him feel more dependent on you. He should follow his example in doing things at ordinary times, and then try to guide her to learn from you and tell him more. Interesting thing. Take him to do more parent-child activities. Personally, I think such children will become more cheerful and confident, but not as you said.
