Last name is Geng. Give your family a name.

Geng Jinyu (idiom "holding gold and cherishing jade" is a metaphor for noble morality)

Ancient people often focus on the meaning and aesthetic conception of names, and often take words from the source, mostly ancient books and literary masterpieces, and even "men must sing, women must read the Book of Songs; The traditional saying that "literature must be the Analects of Confucius and martial arts must be the Zhouyi". Therefore, as a written symbol, a name can't determine a person's fate as some fortune-tellers and geomancers say, but it embodies the spirit of history and culture, the information of the times and society, the brand of family lineage, parents' deep love and ardent expectations for their children, and different ideals, interests, hobbies and goals, which have a great subtle influence on life. I wish you a good name as soon as possible.
