What do you mean by Xiao Qingxin and Yu Jie?

"Xiao Qingxin" originally refers to a type of music known for its fresh, aesthetic and casual creative style, also known as indie pop, and then gradually spread to various cultural and artistic fields such as literature, film and photography. Nowadays, this style, which was quite small at first, has gradually formed a subculture phenomenon, which is sought after by many young people. In China, a group of young people who prefer fresh and beautiful literary works and whose lifestyles are deeply influenced by fresh styles are also called "Little Fresh". Whether as an ideal lifestyle or as a beautiful artistic conception that people yearn for, Xiao Qing-xin exists with the characteristics of elegance, naturalness, simplicity, detachment and tranquility. Written in Japanese as "ぉねぇ", it means a respectful title for elder sister, and it is extended to refer to young women with mature appearance, figure and personality, as well as girls or young women with certain personality (generally 20-36 years old), whose height is generally above 160cm. Compared with lolicon and space, those who prefer royal elder sister are often called "royal elder sister". In addition, "Yu Jiekong" may also be the younger brother in the relationship between sister-in-law and daughter-in-law.
