As this is the first time Sheung did this, Ngo wants him to suffer and so makes him wear a lamp on his head. During the Lantern Festival, the Emperor has fun with his officials. After a few drinks, Bo says that Ngo has lost the virtues of a woman. Ngo immediately appeals to the Emperor. All the women there, including the Empress, say that Bo should be punished. Bo is unhappy and invites his cousin, Kam Cho, seduce Sheung to make Ngo unhappy. Sheung, a philanderer, schemes to take Cho as his concubine. Ngo finds out and beats him. Bo urges Sheung to divorce Ngo. Ngo is furious and lodges a complaint with the imperial court. The Emperor allows Sheung to have a concubine.
