A post-90s boy who relied on lazy fish to turn around.

In 2012, the 24-year-old worked in Ningbo after graduating from college, earning 2000 yuan a month, making him a Neet. He returned to his hometown to start a business and set his sights on an interesting fish. When he encountered difficulties, he was at a loss as to what to do; at the first taste of success, he was in high spirits. Look at the post-90s boy Lu Zehui, how to use wisdom and practical work to become a leader in the local industry in three years.

Lu Zehui: it's not too loud. Crabs don't know how to run.

Interviewer: a lot.

This young man named Lu Zehui is different from others in catching crabs. Instead of catching crabs during the day, he has to catch crabs at night.

Lu Zehui: during the day, as soon as you walk past that crab, it basically runs away. Because it's night, just like people, I feel like I'm resting after climbing up, and it's easier to catch it when I catch it, so don't stimulate it even with the bright light. Once a strong light stimulates the crab, it is equivalent to waking up, and it will be harder for you to catch it.

Lu Zehui told us that according to the crab's habits, crabs will always be in the water before the end of September and after December every year. In October and November, crabs come ashore at night.

Reporter: I think there are some crabs whose pliers stand up easily.

Lu Zehui: just like that cobra. After you frighten it, its head will stand up. This crab has the same characteristics. After you frighten it, its two pliers will turn upside down. This is going to be, if you touch it again, it will attack you. If you catch it, you will definitely be clamped by it, right? It is sure, you see, it will definitely touch you, so this crab is still very aggressive. You see, if you slowly don't look at it, it will stand up and put the pliers down.

Today, Lu Zehui's customers want large size crabs, four taels of male crabs and twenty-eight female crabs.

Interviewer: is this all right?

Lu Zehui: I can't do this. It's too small. I can only estimate it by two or three at most.

Interviewer: pretty much.

Lu Zehui: the one on your right is a little bigger. This one may be three or two halves.

Interviewer: it feels about the same.

Despite the fact that there is only a half-two difference, there is a big difference in the price of crabs. Three-and-a-half male crabs sell for 70 yuan per jin, while four taels of male crabs sell for 120 yuan per jin.

Lu Zehui: there should be more than ten or twenty jin. Don't look at these ten or twenty jin. Even these ten or twenty jin can be sold for 300020 yuan per jin. They are very popular and the price has been rising all the time. Now basically one price a day, that is, an increase of five yuan a day, an increase of five yuan a day. This crab is quite big, this crab is four taels, and that's how it can be sold on the market. Now because there are few big crabs in the market.

Lu Zehui, who was walking in the village in early 2012, did not expect that he came back here a few months later. The reason is that after graduating from the computer application major of Ningbo City Vocational and Technical College, Lu Zehui stayed in Ningbo to work with a monthly salary of more than 2000 yuan. Soon after, Lu Zehui discovered the business opportunity and decided to return to his hometown to start a business. in just three years, he became the leader of the local crab farming industry. He took the lead in experimenting with a new way of raising crab ponds, raising the income per mu of crab ponds from 4,000 to 5,000 yuan to more than 10,000 yuan.

Chen Chao, mayor of Hongqiao Town people's Government, Changxing County, Zhejiang Province: he chose to go back to his hometown to start a business, which injected new vitality into our entire river crab industry. Last year, we tried to raise about 50 mu, and the people saw his benefits. so the enthusiasm of farming has also increased this year, to 3000 mu.

The scene of the son rowing and the father fishing has been repeated for many years. However, since 2012, Lu Zehui has stopped his father from breeding because he thinks his father's farming method is too traditional.

Father Lu Xinquan: when the silver carp seedlings are put down, some of the fish have grown up, but they are worthless. The crab will look at the sky at the end of the year. Some are still in their prime, but others are at a loss.

Lu Zehui refused to let his father raise any more, but he quit his job and came back to continue crab farming. In March 2012, Lu Zehui persuaded his parents to support him and helped him raise 600000 yuan to build more than 100 mu of crab ponds. His parents could not help but let Lu Zehui try. This father has not made any big money for more than ten years. Can he be a college student who has just entered the society and is still a little immature?

Crabs, prawns and mandarin fish are generally raised separately, but Lu Zehui found that the combination of the three is very popular in the area, and he does the same. At that time, Lu Zehui was in high spirits and felt that he had a foundation and could endure hardships, so it was no problem to make money.

Lu Zehui: just came back, how about thinking a little high? I think if I do this job, I will certainly pay more attention than them and notice what they don't notice. Then I think I can definitely do better than them in many ways.

After intensive culture in the crab pond, the survival rate of crabs was 30% higher than before, and Lu Zehui's confidence soared. But soon after, in September 2013, Lu Zehui discovered a phenomenon. There were some idle crabs on the ridges outside the farm. Where did this come from? Soon, Lu Zehui became vigilant. It turned out to be his own crab. Lu Zehui wondered, although burrowing is a habit of crabs, other crabs are fine. Why do their own crabs make so many holes and run away?

Lu Zehui: mud ridges 3 to 5 meters wide will be easily pierced by crabs. After drilling a hole like this, the crabs are all lined up and will run a lot for you in a few days.

Interviewer: can't it be blocked? Is it too late?

Lu Zehui: block it. This is to cure the symptoms rather than the root of the problem. If it is blocked, it may be all right for a while, and in another week or two, there may be another hole in another place.

After inspection, Lu Zehui found that the crabs in two crab ponds were basically gone, losing 60,000 to 70,000 yuan. Over the course of a year, Lu Zehui lost money for a long time and went to start a business with his parents' hard-earned money, but this situation came to an unspeakable pain in Lu Zehui's mind.

Lu Zehui: I feel like a loser. I'm sorry to them. I feel ashamed that I didn't do well what I had planned.

At that time, Lu Zehui was under a lot of pressure. he often observed in the crab pond and wanted to find out why the crabs burrowed and escaped. The reason is actually a complex chain reaction, and the fundamental problem is related to mandarin fish. This is the underwater world of crabs, prawns and mandarin fish. Although this mandarin fish does not harm crabs, it will indirectly affect the aquatic plants on which crabs live.

Lu Zehui: at the beginning, it is a special small fish, wild miscellaneous fish for mandarin fish to eat, once mandarin fish are not cultivated well, those wild miscellaneous fish will survive in large numbers, and reproduce very quickly, and in the later stage, there will be a lot of damage, and all the roots of aquatic plants will be cut off.

After the aquatic plants died, the crabs gave full play to their nature and desperately burrowed everywhere.
