At the Flower Festival, Lau Yuet-ying falls in love with Bin Kei at first sight. Chun-lan, her maid, helps match them, but servant Mung Luk sends the invitation letter by mistake to Chau Tung, a rogue, instead of Bin Kei. Chun-lan comes by boat at night to visit Bin Kei and advises him to dress as a woman when visiting Yuet-ying. As Yuet-ying can’t finish Bin Kei’s embroidered shoes in time, Chun-lan gets a pair of new shoes from Madame Lau by a trick.

By mistake, Chau Tung grabs Bin Kei home when Bin Kei sneaks in Yuet-ying’s house as a flower-girl. Fortunately, Bin Kei flees before the wedding night and goes for the imperial examination. A year later, Chau Tung comes for Yuet-ying again and finds that the bride Lau Ka-ling took away is in fact his sister Chau Yuk-lau. Meanwhile, Bin Kei comes home as the top scorer in the imperial examination. After teaching Chau Tung a lesson and expressing his gratitude to Chun-lan for being his match-maker, Bin Kei and Yuet-ying become a happy couple finally.

After encountering the Holy Matron while travelling for the imperial examinations, Lau Yin-cheong falls in love with her. They have a son named Cham-heung. Although they live a happy life, they have no idea that the Holy Matron’s elder brother, God Erlang, would discover their forbidden love. The God Erlang is enraged, therefore, when Cham-heung is just a month old, he leads the heavenly generals to despoil the lotus lamp and hunt down the Lau family. Lau Yin-cheong and Cham-heung would have been executed if the Immortal Thunder had not forewarned the God Erlang that the father and son are both mortals and that he cannot punish them. Therefore, God Erlang only imprisons the Holy Matron beneath the Mount Hua and lets Cham-heung and his father go. Out of sympathy, the Immortal Thunder saves Cham-heung and instructs him in martial arts. After fifteen years, Cham-heung grows up into a brave young man. The Immortal Thunder gives Cham-heung an axe as a gift and tells him about his true identity. After learning the truth, Cham-heung goes to the Mount Hua to save his mother and battles God Erlang. In the end, husband and wife, mother and child are reunited.
