The most precious gift

In fact, we in China did not have glass mirrors, we used copper mirrors. By the time of the Ming Dynasty, glass mirrors were not so rare in foreign countries, but they were still very new in China.
On this day, a British merchant ship docked at Quanzhou Harbor, and the crew went to the city to drink. A crew member spent all his money, basking in the sun against the wall on the street, taking out a small mirror only the size of a palm, and playing against the sun to reflect the light into the eyes of pedestrians.
At this time, a salt merchant was walking in the street, and the sunlight reflected by the glass mirror shook his eyes. He was very angry, went to a closer look, found that it was a foreigner, and the anger in his stomach was more than half gone, when he saw the sailor holding a small baby in his hand, the fire was completely gone, he asked the sailor to take the baby, held it in his hand, looked in the mirror, and was shocked: I saw that inside the baby there was a goblin who looked like himself with wide eyes looking at him curiously, and he was scared to throw the baby away subconsciously. The baby fell onto a rock and broke into five pieces with a bang.
The sailor was so poor that only this small glass mirror was left, and now the mirror was broken, he was so anxious and angry that he crouched down and picked up the pieces of the small mirror one by one, and then stuck them to the salt merchant, asking the salt merchant to compensate him.
After asking, the salt merchant realized that the object was a mirror, which had the same function as the copper mirror in China, but was a hundred times clearer than the copper mirror. So he took the fragment of the mirror from the crew's hand, gnashed it with his teeth, licked it with his tongue, and smelled it with his nose. He reflected the sun's light like a child today, and found that each fragment could reflect the scenery and characters of himself and the outside world. So the salt merchant happily led the sailor home. The salt merchant told the butler to call his four wives and give each one a piece of glass mirror. Those wives have never seen this thing before, and they are so happy that they do not know how to be good, and they are winking at the fragments of the mirror, not to mention how rare. The salt merchant had plenty of money, and when he saw his four wives happy, he was a little carried away. He looked at his happy and excited face with the remaining piece of mirror, and with a wave of his big hand, the butler understood the master's meaning, so he generously compensated the crew with a lot of gold and silver, and let the crew use a large package to "pocket" away.
The sailor unexpectedly got a lot of gold and silver treasure, almost beautiful, carrying a large package, humming a little song back to the ship, shake the package, to show off to the other crew. The captain asked what was going on, and he began to think: This guy used a broken glass mirror to get back so much gold and silver treasure, if I use some strange mechanical things, I can certainly get back more good things. He made up his mind and went to sleep peacefully.
The next morning the captain gathered a few things, wrapped them in a cloth, carried them on his back, and went to the salt merchant's house. He opened the package and showed the salt merchant its contents: a telescope, a pocket watch, and a globe. After the demonstration, the captain taught the salt merchant how to use a telescope and a watch, then told him what a globe was, and finally said that these things were for the salt merchant. When the salt merchant saw that the captain had given him so many good things, he was so happy that he danced and told the butler to give his most precious things as gifts to the captain. The housekeeper promised and went to prepare the gift.
After a while the butler came out of the room with a small red chest in both hands, and solemnly handed it into the captain's hand. Seeing this little chest, and supposing that it contained something very, very valuable, the captain, his hands trembling with joy, took the chest, bowed to the salt merchant, and went away contentedly.
The captain returned to the ship, and with great excitement opened the red chest, which contained a little orange box; Open the little orange box and inside there is a little yellow box; Open the little yellow box, inside a green cloth bag; Open the green cloth bag, there is a green cloth bag inside; Open the blue bag, there is a blue bag inside... At last, the captain opened the purple cloth bag --

Inside was a shard of a glass mirror.
