Tens of millions of wealth starts with the discovery of the "face" of crabs.

This is South Taihu Lake in Huzhou City, Zhejiang Province. In late November, the sale of crabs in the Yangtze River Delta is coming to an end, while here in Song Liangliang, a large number of crabs have only just begun.

On November 22, Song Liangliang was going to catch a batch of crabs. Dealers who came to visit the crab breeding base saw the process of catching crabs with their own eyes for the first time. They were very curious and began to discuss the ground cages to catch crabs.

Deputy general manager of Jiaxing District, Zhejiang Province, an express group: if it climbs, why not climb outside, but must get into the net?

Song Liangliang: the crab crawled along the net, climbed into the net and came in.

Deputy general manager of Jiaxing District, Zhejiang Province, an express group: it is equivalent to that the only way out is in front of this network.

Song Liangliang: yes, the only way out is here. As soon as you climb here, you go in, and then you come over.

Deputy general manager of Jiaxing District, Zhejiang Province, a certain express group: all come to this end.

Song Liangliang: yes, yes.

Deputy general manager of Jiaxing District, Zhejiang Province, a certain express group: then there is a trumpet that can get in but not out.

Song Liangliang: yes.

E-commerce: I thought the crab was raised vertically, but it was horizontal.

As soon as the crabs were caught, Song Liangliang began to be busy. He wanted to sort the crabs for the first time.

Song Liangliang: the female crab is put here, the male crab is put there, and the male and female are separated first.

Dealers admire Song Liangliang for his speed and skill in catching crabs.

Deputy General Manager of Jiaxing District, Zhejiang Province, an express group: how many years have you been practicing this crab-catching technique? How many years have you been doing it?

Song Liangliang: I have been doing it for about 20 years.

E-commerce: how much have you raised now?

Song Liangliang: now our entire cooperative covers more than 1000 mu.

After raising crabs for more than 20 years, Song Liangliang was not only very adept at sorting crabs, but also developed the unique skill of catching crabs.

When the crab fishing came ashore, Song Liangliang began to sort the crabs for the second time. When Song Liangliang saw that Song Liangliang caught the crabs with a certain accuracy, the tourist wanted to compete with him.

Deputy general manager of Jiaxing District, Zhejiang Province, a certain express group: catch one, catch one to take a test, the thickness is different, you can't just look at the width.

Song Liangliang: how about this?

Deputy General Manager of Jiaxing District, Zhejiang Province, an express group: aren't you very good? how much is this?

Tourist: I can't.

Deputy general manager of Jiaxing District, Zhejiang Province, an express group: you can, don't be modest.

Tourists: 3 taels, 3 taels.

Song Liangliang: wait a minute.

Tourists: 2 taels 9.

Deputy general manager of Jiaxing District, Zhejiang Province, a certain express group: he said 2 two 9.

Song Liangliang: 3 taels 6.

Tourist: how can it be so high?

Song Liangliang: three taels and five, right? the difference is a penny. I say it is a penny. I only have an error of one penny.

Deputy general manager of Jiaxing District, Zhejiang Province, a certain express group: the boss was a little ruthless, and this was thrown into the 4-tael bucket.

Seeing so many crabs, some little tourists couldn't help themselves and caught them by themselves.

Tourist: dad, I really want to steal the scene. I want to steal the scene.

Taking advantage of the large number of people, Song Liangliang began to introduce the crabs he raised.

Song Liangliang: our crabs are so powerful that they bite all the snails like this. Its pliers are very strong, it can break this foot, you see, the foot has been broken. Look, the hands can be dangerous.

Tourist: the foot came down and was bitten off directly.

Song Liangliang: if you touch it, it will clip it, so be careful when you grab it. You can't grab it from the front.

These dealers and tourists were specially invited by Song Liangliang. Starting from the crab listing every year, Song Liangliang's breeding base is always full of people during the lake opening festival and special days, and it is often more lively than it is now. By selling crabs, Song Liangliang's sales reached more than 20 million yuan in 2014. Local farmers told reporters that privately, everyone called Song Liangliang "the boss of Taihu crabs."

Farmer: boss Song must be the boss of our Taihu crab. He has a large sales volume, a wide range of outside channels, many customers, good quality and high credit. If he asks us to hoard crabs, we will hoard crabs. If we don't hoard, we won't hoard. I'm sure we'll listen to him and keep making money year after year.

Farmer: he can keep an eye on the market. He sometimes tells us to sell it, but when the market is bad, we basically sell it right away. He said wait a minute, and the price will go up, so we'll sell it a little slower.

Now, however, Song Liangliang invites these dealers and tourists to his breeding base, losing a lot of money each time.

Song Liangliang: it's very compensatory. Four times a year, the daily compensation is worth about 8,000 yuan. If you do it often, you will lose seven or eight thousand yuan a day, which is a large figure in a year.

If he doesn't make money but loses money, why did Song Liangliang do it?

When Song Liangliang was 4 years old, something broke the heart of his family. He vaguely remembers that year, because his family was poor, his parents sent him to another family to live.

Song Liangliang's father: life was hard, and he finally took it away.

Song Liangliang: when I was a child, you sent me out, you have difficulties, I will not ask, but after all, I still want to come back, I am the idea, always want to come back.

At the age of 16, Song Liangliang returned to his biological parents after consulting with his adoptive parents. At this time, he found that his parents had been drifting on such a boat for many years to make a living by fishing for small fish and shrimp. He was secretly determined to find a stable home for his elderly parents on shore through his own efforts.

Song Liangliang: when I saw the children on the shore playing, they all had a home. We only had a boat. When we were young, our hope was to live in a small house. I started my own business and started my own business at the age of 19.

At the age of 19, Song Liangliang came to Guangdong alone to sell crabs, and the price of crabs in the Guangdong market gave him an insight into a business opportunity.

Song Liangliang: at that time, our crabs sold for more than 120 yuan per jin in Guangdong, but they could sell for more than 200 yuan per jin, twice the difference. But they can do it. After I saw the price difference, I went to learn.

After careful observation, Song Liangliang found that the method of sorting crabs by others was very rare.

Song Liangliang: we used to be like this here, how big this one is thrown here, how big that one is thrown there, they are not like this, a bunch of crabs are put here, they all want to see it like this. I said that I am very surprised that they pick crabs and what they do.
