Pevichka Li Soo-lan for a walk gets acquainted with the syutsay Li Bin, nicknamed Jade Vase. Binh takes Su-lan for maintenance.

Hangzhou official Tao Bo-chan calls in on his friend Lee Binh and persuades him to think about a career. But he cannot part with the sweetheart. Then Tao takes his work to the capital.

Li Bin spent all his money. Mistress Su-lan brings a new customer - a Shanxi merchant Shen She, nicknamed Black Shen. He has wealth - 30 carts of wool and silk. Meanwhile, Binh and Soo-lan continue to passionately love each other. Sul-lan painted the painting “An Orchid in a Vase of Jade” (“Doe” means “Orchid”), and he composed a song based on the motif “Jade Vase in Spring”. At this moment, the mistress appears with the merchant. Binh is forced to leave the house. Then Su-lan cuts her hair and vows not to belong to anyone but Bin.

A friend of Su-lan, the songwriter Chen Yu-ying, arranges a date for lovers. While they pour out their feelings, again are the mistress with the merchant. Bin scoffs at his ignorance and rude appearance, but he repeats everything about his 30 carts. Finally, the hostess drags Li Bin to the judge. It turns out to be Tao Bo-chan, appointed ruler in Jiaxing. He takes everyone into the presence.

Tao Bo-chan announces that the emperor, after reading the composition of Li Bin, appointed him an assistant to the ruler of Jiaxing. He rejects the claims of the hostess - after all, Li Bin has long loved Su-lan. Nevertheless, he advises Bin to pay off the mistress. Merchant Shen She gets 40 sticks. The last obstacle to the lovers' path also disappears - the same surnames: it turns out that Su-lan is actually from the Zhang clan.
