1. The "fat" in "Plums, golden apricots, fat" means that the apricots have grown up and are very full, and are almost ready for a good harvest.
2. "The plums are golden and the apricots are fat." The author of this poem is Fan Chengda, a poet of the Southern Song Dynasty. The original text is: The plums are golden and the apricots are fat, the wheat flowers are snowy and the white cauliflowers are sparse; the day is long and no one passes by the fence, but only Dragonflies and butterflies fly.
