To give you a good reference, "Si Fei", these two words contain the parents' expectations for their daughter to be studious, thoughtful and morally pure, and hope that their children can be as ambitious as "the swans think about flying" Keep it high and far away and moisten things silently like "rain and snow falling down".
The person who "thinks" means wisdom - "Shuowen Jiezi", people who are diligent in thinking are wise, so it is said that "learning without thinking means nothing"; as a verb, it means thinking, which refers to many things. Affectionate yearning for lovesickness, such as "Young and green Zi Jin, I think about it for a long time"; in addition, it also includes the pursuit of moral cultivation. The "Shu Yao Dian" notes: "Moral purity is called thinking." "Fei" refers to the appearance of rain and snow - "Shuowen Jiezi", so the chapter "Caiwei" says "rain, snow and rain". Rain and snow are the spirits descended from heaven. They are not only the natural beauty of heaven and earth, but also the source of nourishment for all things. And "霏" is homophonic to "fly", soaring into the sky and having lofty ambitions. The high-flying ambition of "the swan is flying" is preserved in the gentleness and elegance of "the rain, snow and falling rain", which can be said to be out of the ordinary.
