One year, Lu Ban, a craftsman from Shandong, brought his little sister to Hangzhou. They rented two shops next to the Qiantang gate and hung the sign "Shandong Lu's, made of iron wood and stone". As soon as the sign was hung, those who came to worship the master broke the threshold. Lu Ban picked and selected, and took 180 young descendants who were ingenious and took them as apprentices.

Brother Lu Ban's craftsmanship is very clever, it is really ingenious: the hewn stone dog can manage the door, and the carved wooden cat can catch mice. One hundred and eighty apprentices have become experts after their guidance.

One day, Lu Ban was carefully teaching his disciples how to live, when suddenly a black wind blew, and the sky suddenly turned dark clouds. It turned out that a black fish spirit came to the world to haunt the world. Black fish spirit drilled into the middle of the West Lake, a deep pool of 360 meters in Hangzhou. It blew in the deep pool, and Hangzhou was full of fish and stench; it sprayed water in the deep pool, and it rained heavily in the northern mountains and southern mountains. On this day, the willows by the lake broke, the flowers withered, and the water kept rising.

Lu Ban and his disciples climbed the mountain together. They looked down at the mountain and saw that there was a sea in front of them, the houses of the whole city were soaked in stinky water, and men, women, and children fled to the hills around the West Lake. In the middle of the lake, there was a big and big whirlpool, and a very wide and wide fish mouth was tilted up in the whirlpool, and the fish mouth was rising higher and higher, slowly revealing the whole big fish head. The fish head rose up, and suddenly a dark cloud flew up and rose to the sky. The dark clouds floated, drifted to the top of the gem, and slowly fell down, and a black and ugly descendant emerged from it.

Blackie rolled her cockfighting eyes and glanced at Lu Mei: "Ha! pretty big girl, what are you doing?"

Lu Mei said, "Ask the girl what she does, the girl is a clever craftsman."

The black queen looked at Lu Mei from head to toe: "By the way, by the way, I see your bright eyes and curved eyebrows, you must be able to cut silk and satin skillfully. Come, follow me to make new clothes."

Lu Mei shook her head.

Hei Housheng looked at Lu Mei from her feet to her head: "By the way, by the way! I see your slender and slender hands, you must have good needles and thread for drawing dragons and embroidering phoenixes. Come, follow me to embroider the quilt."

Lu Mei shook her head.

After thinking for a moment, he narrowed his eyes and said, "Beautiful big girl, it doesn't matter if you can't cut or embroider. You can marry into my house.

Lu Ban separated his hand with a hammer and shouted, "Get out of the way!"

"My skin is three feet thick, so I'm not afraid of your hammer! If the big girl marries me, it's easy to talk about anything; if the big girl doesn't marry me, the water will rise all over the mountains!"

Lu Mei thought in her heart: If the water rises again, the lives of the whole city will not be saved. She rolled her eyes twice, and she had a solution. She said to the black newborn, "It's not urgent to marry you, let my brother do a dowry for me."

Black Hou Sheng was happy when he heard that: "Good girl, I promise, what kind of dowry do you plan to do?"

"High mountain, high rock, I want to ask my brother to chisel it into a big incense burner."

Black Hou Sheng patted his thighs happily: "Okay, okay, okay! King Blackfish in the sky, Luo Fan stands in the temple. There is a stone incense burner for your dowry, just take it to provide for it!"

Lu Mei pulled Elder Brother over and discussed for a while. Lu Ban said to the black newborn, "East is water, west is water, what should I do? You can drop the water first, so that I can do it."

Black Hou Sheng opened his mouth wide and sucked, and the water in the city flew up and poured into his belly.

Lu Ban pointed to a cliff on the mountain and asked Blackie, "Look, look, how about chopping down this mountain and chiseling an incense burner?"

"Okay, okay. Brother-in-law, hurry up and chisel, the bigger the chisel, the more beautiful it is!"

"The incense burner is high, the incense burner is big, and how do you move the heavy stone incense burner?"

"Well, as long as I lift my foot, there will be a black wind behind me; what is a small stone incense burner, even a mountain I can suck!"

The people who were hiding on the surrounding mountains all went home, and Lu Ban and the others climbed up the upside-down cliff. Lu Ban swung his big hammer and hit the first hammer on the cliff: one hundred and eighty of his apprentices followed suit. With a "boom", the cliff rolled over. - From then on, there was a cliff left on the gem mountain by the West Lake.

The cliff is really big, looking at Baiyangyang here, looking at Yangyangyang there, how can you chisel it into a round stone incense burner? Lu Ban looked at the deep pool in the center of the lake, estimated the size, and squeezed a long rope. Standing in the middle of the cliff, he asked his sister to tighten the other end of the rope, "Pa Pa Pa Pa" ran around himself for a week, and Lu Mei's footprints drew a circle on the cliff. Lu Ban first chiseled a large sample, and one hundred and eighty apprentices chiseled according to the pattern. Chiseling one day, another day, a total of seventy-seven and forty-nine days, the cliff was gone, and it became a big stone incense burner. Under the incense burner with a round drum, there are three pointed feet in the shape of upside-down gourds; on the pointed feet, there is a round hole with light on three sides.

The big stone incense burner was hewn, and Lu Ban said to the black descendant, "Look, look, my sister's dowry has been done, please move down to the lake now!"

The black queen wants a bride. Lu Ban said, "Don't be busy, don't be busy, you first move the dowry and put it up, and then send the sedan chair to carry it."

Hei Hou Sheng was so happy that he turned around and ran down the mountain. The whirlwind he rolled up actually sucked such a big stone incense burner and rolled it behind him. Hei Hou Sheng ran and ran, ran to the middle of the lake, turned into a blackfish, and got into the deep pool; the stone incense burner rolled and rolled, rolled to the middle of the lake, slid on the inclined surface next to the deep pool, and "shot" suddenly turned upside down, covering the deep pool tightly, leaving no gap.

The black fish essence was covered under the stone incense burner, and it was so stuffy that it couldn't breathe. When it went up to the top, the stone incense burner did not move at all.

The black fish essence finally suffocated at the bottom of the lake, and the stone incense burner was also stuck in the mud at the bottom of the lake, only three gourd-shaped feet were exposed to the lake surface.

Since then, the West Lake has left a wonderful scenery: every year on the night of the Mid-Autumn Festival, people row to the middle of the lake and light candles in the three-sided round hole at the foot of the furnace; the candles reflect in the lake, and several moon shadows appear. Later, this place was conveniently called "Three Pools Yinyue".
