Square dance next door, Miss Sister.

15-year-old Zheng Xiuzhen has a childish face. She looks very pure, like a little sister next door. She is a little girl that everyone loves. 19-year-old Hua Sha is completely different. She has a strong aura and temperament of a big sister. She cut her hair short, adding a bit of handsomeness to her not-so-sweet appearance.

First, Zheng Xiuzhen. Zheng Xiuzhen's family conditions are very good. She has dual nationality, so she has learned a lot since she was a child and her temperament is different. Zheng Xiuzhen was visiting a department store with her family when she was discovered by a scout of SM Entertainment Limited, along with her sister Jessica. Although the company was very interested in her and decided to train her, because she was less than ten years old at that time, the brokerage company didn't formally sign a contract with her until after she graduated from primary school and arranged for her to enter the company for training.

Jung Soo Jung's father is a boxer and her mother is a mechanical gymnast, so she inherited her parents' excellent genes. She is not only as pure as the young lady next door, but also a good student with excellent academic performance. She 15 years old officially debuted as a member of the women's group f(x) and quickly became popular. However, she did not relax her demands on herself, but took care of her career and studies at the same time. When other stars choose to give up their studies because they are too busy, she still takes time to finish her homework during the break of the program.

Because of her sense of responsibility and strict self-discipline, Zheng Xiuzhen strives for perfection in everything. She never slackened off in her career, singing and dancing, and her studies. When she graduated from high school, she was the only art student who won an academic award and was admitted to Hanyang University and Sungkyunkwan University. Jung Soo Jung is famous and rich, but she has never relied on her family and always worked hard on her own, so she is deeply loved by netizens.

Second, Hua Sha. Huasha had a dream of being a singer since she was a child, so she began to imitate singing at an early age and began to imitate and practice popular star songs from junior high school. Because Huasha insisted on taking the personality line since she was a child, she dressed differently. She always has the temperament of a big sister, giving people a generous and cool feeling.

Later, after several years of hard training, Lisa finally made her debut in MAMAMOO. However, after her debut, her career did not improve much. On the contrary, the appearance of Hua Sha broke the traditional impression of fans that the hostess loves beans, because she is not sweet, has the temperament of a big sister, has an iconic jazz voice and an informal personality, and her light makeup does not match the image of the women's group in the public impression, so she was asked to quit the group.

However, Huasha touched everyone with her frankness and gained a large number of fans. When facing the camera, she did nothing, being herself honestly, which narrowed the distance with her fans and made them feel that the gas field on the stage in her life was completely different, so that everyone could see her other side. It is this undisguised truth, like a clean stream, that makes fans like her more and more.
