Bassanio was a gentleman of the poor, living on debt. Antonio was a rich man, but it happened that the money was used for the goods of the voyage. He thought that he could return to his capital in two months and make a lot of money, but the ship full of goods had an accident. Even when Bassanio finally begs to pay Shylock three times the cost, Shylock is still unmoved. When the case was brought to the Venetian court, the judge, the duke, even begged for mercy for Antonio, but the case went on as before, because at the last moment Shylock did not show his mercy. Shylock's hatred and resentment towards Antonio can be seen from the following words: "He has insulted me, robbed me of hundreds of thousands of businesses, ridiculed my losses, ridiculed my gains, insulted my nation, destroyed my business, divided my friends and incited my enemies; What's his reason? Just because I'm a Jew."

The outcome of the lawsuit is that Portia disguised as a doctor of law, using a loophole in the loan contract, that is, when the meat can not shed a drop of blood, finally let Shylock half of the property to his daughter and son-in-law. In the end, the three couples get married and their friends get together.

The union of Portia and Bassanio is accidental, but in the case of the Merchant of Venice, of course, it implies inevitability. According to the will left by her father, Portia could only marry the gentleman who had chosen the three boxes with her picture in them. The boxes were made of gold, silver, and lead, on which were written three words: "Who has chosen me, shall have what everyone desires; ② He who chooses me shall receive as much as he deserves; Whoever chooses me must be prepared to sacrifice everything he has. The selection of these boxes was subject to three conditions: (1) No one should be told which one had been chosen; ② if the wrong box is chosen, the final examination shall not propose to any woman; "If he fails, he must leave Portia's place at once. If there are no conditions, I think my personality will choose the third box, but the opportunity cost is too large, I may eventually choose not to choose it. Bassanio finally chose the lead box, which happened to contain Portia's beautiful photograph
