Yin, of Chinese origin, means 'hidden' or 'secret'. It is one of the two fundamental principles of Chinese philosophy, alongside Yang, representing the feminine and passive aspects of life. In ancient China, Yin was associated with the moon, earth, water, cold, darkness, and femininity. This name has gained popularity in recent years worldwide, often chosen for its unique sound and cultural significance.
"Yin was quite popular with parents in the late 1970s and early 1980s, with a total of 13 babies named Yin born over those years."
