Shen Yan, a single banquet, is long and clear. Shen Yan's name is taken from a poem in Bai Juyi's Pipa, "Move the boat closer to the boat, invite her to dance, call the wine lamp again, and have a new banquet". Banquet symbolizes happiness and leisure. And Shen Yan's words "Long Ming", Long Ming, this lamp, once burned, can't be blown out until the oil is exhausted. It conforms to the meaning of "gathering more wine and lanterns to start our party again"
In the original book, although Liu Ling is a princess favored by the royal family, her life is full of depression and darkness, and the appearance of Shen Yan is the only light in her life. It was Shen Yan who lit up her life and pulled Liu Ling back from despair again and again.
