Xuanzang returned to the temple in tears and told the abbot that he was leaving at once for Hongzhou. When he reached the Ten Thousand Flowers Inn he said to the innkeeper Liu the Second, “How is the mother of Prefect Chen of Jiangzhou who is staying in your inn?”
“She used to stay here,” replied the innkeeper. “She went blind, and as she didn't pay any rent for three or four years, she now lives in a ruined tile-kiln near the Southern gate and begs in the streets every day to keep herself alive. That official went away a very long time ago and she hasn't heard from him to this day, though I don't know why.” On learning this he asked the way to the ruined tile-kiln at the Southern gate and found his grandmother.
“You sound like my son Chen Guangrui,” said his grandmother.
“I'm not Chen Guangrui, I'm his son. My mother is Miss Yin Wenqiao.”
“Why have your father and mother not come?” she asked; and he replied, “My father was murdered by a brigand and my mother was forced to become his wife. I have a letter here and a sandalwood bracelet from my mother.” His grandmother took the letter and the bracelet, and sobbed aloud. “My son came here for the sake of fame and glory. I thought that he had forgotten all feelings of decency and gratitude; it never occurred to me that he might have been murdered. What a blessing that Heaven in its mercy did not cut short my son's line, so that I now have a grandson to come and find me.”
“How did you go blind, granny?” asked Xuanzang.
“I was always thinking of your father and longing for him to come back every day,” she said, “but as he never did I wept so much that! lost the sight of both my eyes.” Xuanzang fell to his knees and prayed to Heaven.
“Although I am seventeen,” he said, “I have been unable to avenge my parents. Today I have come on my mother's orders and found my grandmother; if Heaven is at all moved by my sincerity, may my granny's eyes see again.” When he had prayed, he licked her eyes with the tip of his tongue. The licking soon opened them, and they could see once more.
His grandmother looked at the little monk with a mixture of joy and sadness and said, “You really are my grandson-you're the very image of my son Guangrui.” Xuanzang took her out of the kiln and reinstalled her in Liu the Second's inn, where he rented a room for her, gave her some money to live on, and told her that he would be back within a month.
Taking his leave of his grandmother, he went straight on to the capital, where he found Minister Yin's house in the Eastern Avenue of the imperial city. “I am a relation of the minister's,” he said to the gate-keeper, “and I would like to see him.”
When the gate-keeper reported this to the minister, he said, “I am no relation of any monk.” But his wife said, “I had a dream last night that our daughter Man-tang-qiao came home; perhaps he has a letter from our son-in-law.”
The minister had the young monk brought into the main hall, and when the monk saw the minister and his wife he wept and bowed to the floor before them, then took an envelope out of his bosom and handed it to the minister. The minister opened the letter and read it through, then wailed aloud.
“What's the matter, my lord?” asked his wife, and the minister replied, “This monk is our grandson. Our son-in-law Chen Guangrui was murdered by a brigand, who forced Man-tang-qiao to become his wife.” His wife too began to weep bitterly when she heard this news.
“Try not to upset yourself, wife,” said the minister. “I shall ask our sovereign at court tomorrow morning to be allowed to lead an army myself. I shall certainly avenge our son-in-law.”
The minister went to court the next day and wrote in a memorial to the Tang Emperor: “Your subject's son-in-law, the top graduate Chen Guangrui, was murdered by the boatman Liu Hong while going with his family to take up his office in Jiangzhou, and my daughter was forced to become his wife. This Liu Hong has usurped office for many years by masquerading as my son-in-law. This constitutes treason. I beg Your Majesty to dispatch horse and foot at once to destroy this rebellious brigand.”
The Tang Emperor was so angry when he read this that he ordered Minister Yin to set off at the head of sixty thousand men of the Imperial Guard. The minister left the court with the decree and went to the parade ground to muster the soldiers before setting out for Jiangzhou. By setting out at dawn every day and not stopping till night, they traveled as fast as a shooting star or a flying bird, and before they realized it they had reached Jiangzhou, where Minister Yin's army camped on the Northern bank. That night he sent a messenger with a gold-inscribed tablet to summon the deputy prefect and district judge of Jiangzhou. Minister Tin explained the situation to them and told them to call out their troops to help him. They crossed the river together, and surrounded Liu Hong's yamen before dawn. Liu Hong, who was still in his dreams, heard the sound of cannon and the beating of drums and gongs; when the soldiers rushed his residence he was helpless and soon captured. The minister ordered that Liu Hong and his gang should be tied up and taken to the execution ground, while the army was to encamp outside the city walls.
The minister went into the main hall of the yamen and asked his daughter to come out and see him. His daughter, who had been longing to go out, felt too ashamed to face her father and so was on the point of hanging herself.
When Xuanzang learned of this he went as fast as he could to save her, fell on his knees, and said, “Your son and my grandfather have come here with an army to avenge my father. That brigand has been arrested, so there is no need at all for you to kill yourself. If you die mother, I won't be able to stay alive.” The minister too came into the residence to talk her out of it.
“They say that a woman should only have one husband in her life,” she said to them. “I was bitterly grieved at the death of my husband at that brigand's hands, and could not bear the disgrace of marrying his murderer; but as I was carrying my husband's child I had to swallow the shame of staying alive. Now, thank goodness, my son has grown up and my father has brought an army to avenge my husband but how could I have the face to see you. The only way I can make up for it to my husband is to kill myself.”
“My child,” said the minister, “this was not a case of abandoning morality for the sake of material gain. You acted under duress, and did nothing to be ashamed of.” Father and daughter then embraced each other and wept, while Xuanzang sobbed too. “There is no need for the two of you to be so distressed,” said the minister, wiping away his tears. “Today I have captured our enemy, that rebel, and now I must deal with him.” He got up and went to the execution ground.
As it happened, the assistant prefect of Jiangzhou had sent constables to arrest the other pirate, Li Biao, and they brought him in. The minister was very pleased, and he ordered that Liu Hong and Li Biao were to be put under a close guard. They were each given a hundred strokes of the heavy pole, and statements were taken from them about how and why they had committed the wicked murder of Chen Guangrui. Then Li Biao was nailed on a wooden donkey and pushed to the market-place, where he was sliced into a thousand pieces, after which his head was hung up on public display. Liu Hong was taken to the Hongjiang Estuary where he had murdered Chen Guangrui. The minister, his daughter and Xuanzang went to the riverside, where they made offerings and libations to the emptiness and cut out Liu Hong's heart and liver while he was still alive to sacrifice to Chen Guangrui. They also burnt a funerary address.
