During the Eastern Han Dynasty, Lu Ji left his post as the prefect of Yulin and prepared to return to his hometown Jiaxing with his family. On this day, Lu Ji, his family and the Jin Gong ship were busy by the Yulin Sea, carrying some books and clothes to the ship.

The ship was a very common passenger and cargo transport ship in the local area. To the surprise of the boatman, the just-left prefect Yulin had nothing else to carry but a few boxes of books and a few household items. Yu Pu said to Lu Ji, "My lord, a high-ranking official like you, is this all you have? The sailboat goes to sea, and the water is shallow, and there is a danger of capsizing in case of wind and waves. You have to find a way to increase the weight of the ballast."

Lu Ji heard the words and said, "How about I buy two urns of pickles, add some dried bamboo shoots, dried longan, etc., and take them back to my hometown neighbors?"

Could it be that Pu Pu Gongwei: "The amount is still not enough."

Lu Ji was a little helpless. He stared at the beach and suddenly had an idea: "The big rock on the shore is ownerless, right?

The boatman looked at Lu Ji, then at the stone, and said with a smile, "This is the only way."

Yu Zuogong found someone to carry the stone on the boat. Soon after, Lu Ji's ship set sail.

After a while, there was a sudden movement in a stranded broken boat on the shore of Yulin, and two people came out of it. It turned out to be a pair of pirate brothers, Ding Da and Ding Er. The two of them were rampant in Yulin, and after encountering Lu Ji Ren, they were suppressed everywhere. In order not to be caught, the two had to hide in hiding for many years.

Ding Er said to Ding Da in frustration, "Big brother, except for a few old clothing boxes and pickle urns on that ship, I didn't see any gold and silver jewelry hidden anywhere!

After drinking a mouthful, he said, "Use your brain, okay? Which Prefect Yulin left empty-handed? After being an official for so many years, his Lu Ji didn't get any oil or water, so ghosts believed it." Ding Da rolled his eyes and said, "Maybe that stone is a treasure!"

Ding Er was puzzled and said, "That stone seems to have been thrown by the boatman at the beach.

Ding Da thought for a while and said, "He used a deception, this is his genius. The baby must be hidden in the stone, or the stone itself is a rough stone of jade and agate... Think about it, if this deal is made, our brothers will spend it in the future, and we will also be angry that he has been suppressed all these years!" The more he thought about it, the more he felt that he was reasonable, so he ordered Ding Er: "Listen up, find a ship with a similar shape and cabin to Lu Ji's ship. We will follow behind and take advantage of the opportunity."

As for Lu Ji and his party, after they set off, they arrived in Haiyang County with smooth sailing for a few days. Lu Ji had a good friend who worked in the Haiyang County Government Office, and there were some merchants from Yulin in the county. They were grateful to Lu Ji for his fairness and integrity during his tenure, and everyone came to welcome Lu Ji's family to the city to rest for a few days.

This made the Ding brothers who followed them overjoyed. They brought the boat to Lu Ji's side, and after getting acquainted with the boatman on Lu Ji's boat, they put perspiration in the wine and fascinated the boatman. Then Ding Da and Ding Er secretly boarded Lu Ji's boat, but rummaged through all the luggage and found nothing valuable. Angry, he threw the pilot, luggage and pickles on his original boat, and then drove Lu Ji's boat and left with the big rock.

When Lu Ji's family came back, they saw that the boat had been changed, and the messy clothes were scattered with a bag of public parcels on the side, and he kept apologizing. Lu Ji laughed and said, "You don't have to blame yourself, and you didn't lose anything. Besides, they found so many ballast stones! I was worried that I would have to spend more money when I got to my hometown, so I asked someone to move the big stone. Now, I can move all the stones off the boat myself."

After returning to Jiaxing for half a month, Lu Ji was walking on the river embankment when he suddenly found a familiar ship anchored. Lu Ji was puzzled, and saw a person on the boat come out. After looking at Lu Ji under the embankment for a while, he suddenly threw his hands and shouted, "Do you dare ask if it is Lord Lu?" Lu Ji looked carefully again, and then he recognized that it was the manager of a certain family in Yu Lin.

The steward got on the embankment and said to Lu Ji, "The people of Yulin heard that the thieves had robbed the ship that the lord returned to his hometown, and they spontaneously rounded up the Ding brothers, so they really caught them. Everyone wanted to return the lord's things as they were, but the stone was cut several holes by the two thieves, and fortunately it was made up by my master. The people of Yulin asked me to deliver this stone and your other luggage to you."

Lu Ji was very touched when he heard this and said, "Lu's luggage is worthless, and he just did his job in Yulin. A mere stone makes you work so hard… Lu really can't feel sorry for Yulin's parents and villagers!"

A few years later, Lu Ji passed away, and the stone was kept in the courtyard by his family, and the ballast stone had long been known. In Ming Hongzhi's ninth year, the supervisor, Fan Zhi, came over and gently stroked the stone with his hand, but unfortunately, a small hole was rubbed out. He was taken aback and ordered someone to open the hole to check. Unexpectedly, he took out some granular gold and silver from the hole!

Fan Zhi was shocked, and quickly ordered people to find several other holes, and finally found that there were gold and silver particles of different sizes stuffed in the holes. There is also a wax seal note in one hole, which reads: Lord Lu, you have worked hard in Yulin, you are diligent and love people, and I will see it for all. This ballast stone that was recovered from the hands of the thieves makes us admire the adults even more. Now it will be wrong, fill in some scattered silver taels in the hole, for your emergency needs, don't blame! Yulin people.

After reading the note, Fan Zhi sighed and ordered the stone pavilion to be protected and inscribed "Lianshi" to admonish all officials.
