"Go to Gudao, there are many fish and shrimps, and there are many reefs, so you can't catch them in the net." Bo Zhu pointed ahead while rowing. Her rowing posture was very beautiful and her whole body was full of vitality. Except for her feet pinned to the board, she was swinging with the swing of the wooden oars. Her thigh muscles were tightly tense, but her waist was very soft. Driven by her, the boat quickly left the straits and sailed on the sea to advance.

"Don't look randomly!" Seeing Hong Tao staring at him with a smile, Bo Zhu's face turned red again.

"I'll help you row a boat for a while, you're sweating!" Hong Tao's face did not become thinner due to time travel. When he saw that it was exposed, he didn't explain. He took the initiative to come over and took over Bozhu's wooden oar.

In less than five minutes, Hong Tao returned Mu Lu to Bozhu again. This thing looked simple, just pushing and pulling, but after getting started, no movement was smooth, no matter whether it was pushing or pulling. Even if Hong Tao was stronger than Bozhu, he could not effectively paddle the ship, and his palms were so painful that he couldn't accept it. This is technology and skill.

It was about five kilometers from the strait to Gu Island. It was not that the island was so far from the coastline, but that it was on the west side of the strait, and was really less than three kilometers away from the coast. Bozhu was like a perpetual motor, shaking her body slowly. When she began to breathe heavily, the boat also roamed to the edge of the island. Then she held the wooden oar, took off the headscarf, and wiped the sweat from her head. Only then did Hong Tao see clearly that her hair was tied behind her head, with a bun on one side, like two bagels.

"Little fish, little shrimp, throw the net down." Hong Tao didn't say much nonsense, directed the two brothers Boyu and Boxi to throw one end of the ground cage into the sea. Large stones have been tied on it. Relying on their weight, the net will sink to the bottom of the sea. He just needs to grab the rope on the other end. When the net stops sinking, tie a bamboo tube more than one meter long and throw it into the water as a marker.

"It's 7 meters deep?" When Hong Tao came, he treated the hemp rope in a knot every meter. This is a basic skill for fishermen. Whenever they arrived at a strange reservoir and needed to find out the depth of the water, they would tie a knot with a rope, tie a big stone, and row the boat to the vicinity of the nest for detection. This one-meter distance is not concealed. Everyone has their own way of memory. Hong Tao measured it himself, and the right arm from the fingertip to the elbow joint was exactly 50 cm.

"Two feet two feet..." Bo Zhu also picked up a rope, tied it to the stone and sank it down, then lifted it up, measured the soaked area on the side of the ship, giving another answer.

"Oh, is this one foot?" Hong Tao soon discovered the clue. There were two marks engraved on the wood on the inside of the ship's side. The distance between the marks was about half a meter. Could it be that this was a foot from the Song Dynasty?

"Two feet... how long is one meter you said?" Bo Zhu stretched out two fingers, and then asked Hong Tao's unit of measurement curiously.

OK, now that I have something to do, let’s learn about different units of weights and measures first. This is a very important issue. Not only should I discuss it with Bozhu, Hong Tao also called Boyu and Boxi together, teaching them the relationship between one foot and one meter and one centimeter little by little. But the progress is a bit slow, they are illiterate, and they can’t count, and there is no way to talk about addition and subtraction. They are still understandable in the decimal place, but they are confused when they reach the centre.

But it doesn't matter. Anyway, I have to wait here for an afternoon, so Hong Tao simply became their math teacher first. With Bo Zhu, he taught them to memorize the multiplication formula first, and then taught them to write their own names with machetes on the boat board. As for whether it is a simplified or traditional Chinese character, Hong Tao couldn't care about it. He himself couldn't write traditional Chinese characters, so he could just learn it.

The more ignorant a person is, the higher his desire for knowledge. Although Bozhu, Boyu and Bozhai don’t say it, he still attaches great importance to being able to learn to read. So regardless of whether Hong Tao taught correctly, he sat on the board to listen to Hong Tao’s lectures. No one said a word more. He was very honest. Then Hong Tao asked several questions in a targeted manner, such as selling a fish for three cents, how many cents are ten fish for? What about twenty? What about thirty? What about these fish? What about 5 cents are big and small, the small ones are sold for three large ones, and the seven small ones are sold for a total of 30 cents?

These simple arithmetic problems made Bo Zhu and the other three dizzy. After counting the toes and fingers, they were anxious and counting together. They were always unable to count. However, when they calculated the multiplication formulas that Hong Tao taught them, they were immediately happy. Bo Yu stood behind Hong Tao, holding a broken sail to the teacher to catch the sun, while Bo Zhu held a thick porcelain bowl respectfully waiting for the teacher to hand it over when he wanted to drink water. Bo Zhu was not idle either. She washed the turban with sea water and washed it. As long as Hong Tao wiped her sweat, she immediately sent the turban. Each of the three of them was busy, and they didn't delay their studies. The afternoon passed in a blink of an eye. Everyone was still on the boat and memorizing the multiplication formulas. The sun was setting in the west.

"Azhu, it's a big deal!" Suddenly, a shout rang out from the side of the ship, scaring the four people on the ship.

"Grandma! It's all your fault, I forgot..." Ah Zhu was reciting the mantra. After finally passing the fifth and was about to hit the sixth, she forgot all of it. She was so anxious that she picked up her headscarf and threw it at the boat next to her.

"Grandma, I can write my name. Uncle Tao taught me, come and see!" Boyu and Boxia also wanted to show their academic performance when they saw their father, but unfortunately they couldn't pick up the board, so they jumped up in a hurry.

"Uncle Fu, Uncle Huang... Ah... Grandpa!" Hong Tao turned around and saw that Bo Fu, Huang Hai, and Chen Mingen's several small boats were back together. The titles in front were smooth, but they were a little unfamiliar with calling Grandpa.

"Hahaha, let's see what you wrote, um...Moyu, it's right!Moyu...Shrimp? Is this the word "Shrimp in Australia?" Chen Mingen smiled very kindly when he heard Hong Tao call him Grandpa, so he brought the boat over, lay on the boat gang and looked at the words on the board. Some of them knew, but some were different.
