Lan Qing
Take the definition of Qingshui as an example. It comes from the Biography of Liang Shu Liu Zun: "His filial friends are pure and deep, honest and solid, adorned with jade, and handsome in appearance". To describe this boy, his name is poetic, his source is excellent, and he is very talented. Used as a metaphor for boys' names, it means that they are beautiful in appearance, full of scholarly temperament and attractive.
Ruoyun
If the word doesn't have too many definitions, it's just a personal pronoun, but cloud is a word that can highlight the cultural background. Its original meaning is sunshine, which means hope. Everyone knows Ji Xiaolan, but he also became Ji Yun, which has many allusions. Ruoyun Zhang, the actor of the same name, is a very sunny person, which makes people feel safe and brings hope.
Of course, this is just an example. It will be better to choose from the Book of Songs when the baby is born, combined with his date of birth.
