The film tells a story of a fool who travels from the present to the era of Chibi with a box. Lau Chin-wei extracted concepts from "A Chinese Odyssey" and re-wrote the story. The new film "Moonlight Express" may also use his "unique kung fu" for a "time-travel" style narrative. Judging from the current list, several main actors from back then, such as Zhao Wei ("Purple Fairy"), Choi Shaofen ("Iron Fan Princess"), and Kong Yuocheng ("Blind Man"), have reunited in "Moonlight Express", showing that director Lau Chin-wei wants to give the audience another dose of "Chinese Odyssey". Since the name of this film is only one character different from "A Chinese Odyssey", it raises suspicions about their "ambiguous" relationship. However, the lead actor Zheng Zhongji denied any similarities between himself and Zhou Xingchi's previously played "Cho Gin-pao". When asked why he chose the name "Moonlight Express", Lau Chin-wei said that "yue" means "穿越时空" (time travel), and that it is a completely different story from "Moonlight Treasure Box". "Yue" means "to cross over or traverse", and this story is entirely different from "Moonlight Treasure Box".
Although it is not technically a sequel to "A Chinese Odyssey", the story of this film actually comes from two treasures of the Purple Fairy: the Purple and Blue Sword and the Moonlight Treasure Box. Zhao Wei reprises her role as the Purple Fairy, but she is just a supporting character. The female lead of this film is Sun Li as the Rose Fairy. The Rose Fairy, admiring the love between the Purple Fairy and Cho Gin-pao, steals the Purple and Blue Sword, hoping to find that destined love. She helps the male protagonist, bandit Qing Yisai (Zheng Zhongji), obtain the Moonlight Treasure Box, leading to a crazy time-travel story. It can be said that these two celestial beauties are what tie together the story of "Moonlight Express". However, under the direction of the old顽child Lau Chin-wei, one becomes a flower-obsessed character while the other becomes a "celestial祥Linco", clearly a pair of "neurotic fairies".
