Tang Yinyin, the third young lady of the Tang family, has been the favorite of the Tang family since she was a child. She has parents, grandparents, and eldest brother and two sisters. Growing up in such an environment, Tang Yinyin should have been slim and well-educated, but in the end she became a bohemian little witch. Tang Yin Yin has not followed the ordinary path since she was a child. Less than an hour after Tang's mother was pushed into the delivery room, Tang Yin Yin couldn't wait to come out. When he turned one year old, seven-year-old Mu Cheng's two front teeth were leaking, and he was reluctantly dragged by his parents to attend the birthday party. The pink and beautiful little dumpling opened his little hands and begged for a hug. Mu Cheng hugged him under the intimidating eyes of his parents, but he was forcefully hugged and kissed several times, and his face was covered with laughter. After meeting and leaving, Tang Yinyin became Mu Cheng's little tail that couldn't be shaken off, and was known as "the third younger brother of the Tang family".
