This sentence actually expressed a girl's feelings for someone."The sun is the morning, the moon is the evening, and the Qing is the morning and evening" meant that her feelings for this person were always the same, while "the sun and the moon and Qing" meant that she regarded this person as important as the sun and the moon. The meaning of the whole sentence was: "I only love three things in life, namely the morning sun, the setting sun, and you. The rising sun represents the morning, a new day, the setting sun represents the evening, the end of the day, and you are the person I have always loved." The novel I recommend to you is "The Evil Concubine: Please Calm Down, Demon Lord." In it, the male lead also expressed similar love. It's worth reading. I hope you like this fairy's recommendation.
