"I also have children, and my children have had similar problems." This is a self-opening technology, and psychological counselors open their similar experiences with help seekers to visitors. "I understand your feelings and feel anxious for you." Psychological counselors tell their anxious emotions to the help seekers, which is an emotional expression skill; "Now you can catch your daughter's love of telling stories and make an agreement with her: as long as she drinks a glass of water from a cup, she will be rewarded with an animal sticker, but if she drinks water from a bottle, a sticker will be deducted every time. Every night, you and your daughter count the number of stickers your daughter gets. If you have a few stickers, you can tell your daughter a few stories. " This is telling the helper what to do, not guiding the technology.
