It is unusual for returnees to raise turtles.

Program highlights: in 2009, he graduated with a master's degree in business administration from Canada and returned to his hometown to enter a strange industry and raise rare turtles. As soon as he entered the turtle industry, he surprised his peers. High-end turtle species are highly sought after, but he has a crush on the middle and low-end turtles that everyone is not optimistic about. The price of the stone tortoise plummeted and others sold it one after another, but he quickly raised more than NT $2 million to buy it. With this risky move, his sales have tripled in two years. In just five years, he has become a leader in the local turtle industry. What business opportunities did he find? How do you do it?

This is Wu Guozheng's turtle farm. Today, Wu Guozheng wants to clear the pond and sell crocodile turtles.

Reporter: how many tortoises can be produced today?

Wu Guozheng: about 8000 jin today.

Reporter: about 8000 jin.

Wu Guozheng: yes, now because we are doing more and more, the price is about 20 yuan per jin. We still have to see if there is that disabled turtle, because it has to be singled out.

Crocodile turtles are very aggressive and look similar to crocodiles.

Wu Guozheng: first of all, its tail is very similar to the tail of a crocodile. You see, it has this tail thorn. Secondly, it is ferocious like a crocodile, that is, it opens its mouth to attack.

Interviewer: the two have already started to fight.

Wu Guozheng: yes.

Interviewer: got it.

Wu Guozheng: then the third one, these little prickles on its skin are also very similar to that crocodile. So we named the crocodile tortoise after its appearance.

In the concrete sidewall of the pond, there are holes, large and small, which were scratched out by crocodile turtles in less than a year. There are more than 800 crocodile turtles in this one-acre pond, but Wu Guozheng went barefoot to catch crocodile turtles.

The reporter also decided to get close to the pond and learn about crocodile turtles.

Interviewer: if I go down barefoot like this, won't I bite?

Wu Guozheng: no, you are so beautiful, I won't bite you.

Wu Guozheng: be careful, don't be in such a hurry, slowly stand firm, stand firm.

As soon as the reporter got into the quagmire, he couldn't move an inch. He walked like this.

With the help of Wu Guozheng, the reporter was barely able to stand in the quagmire. However, Wu Guozheng not only walked steadily, but also used his feet to sense the position of crocodile turtles.

Wu Guozheng: I step on one now. Now you can grab its tail.

Interviewer: is this a tail?

Wu Guozheng: yes. It has to be big.

Interviewer: this is so big. How heavy is this?

Wu Guozheng: this weighs 15 jin.

Interviewer: you see, as soon as it came out, its mouth opened wide.

Wu Guozheng: yes, as soon as I step on it, I can usually feel it, that is, this shell, its feet are all shrunk, that is, that shell, step on that shell.

Reporter: if you step barefoot, if you step on this hard one, there will be crocodile turtles.

Wu Guozheng: yes.

Seeing that Wu Guozheng was able to catch the tortoise, the reporter also tried to catch the crocodile tortoise with the method he said.

Wu Guozheng: is there any here? Is there? Pick it up if you have it.

Reporter: it won't bite me, will it?

Wu Guozheng: no, don't worry. Grab the tail. Good catch, good catch.

Interviewer: what a big one.

Wu Guozheng: you see, it's a little fierce.

The pond is full of fierce crocodile turtles like this. How dare Wu Guozheng catch them barefoot in the water? The reason has to do with the water.

Interviewer: how fierce.

Wu Guozheng: yes, very fierce. Because it left the water, its attack power was shown.

Interviewer: isn't it so fierce in the water?

Wu Guozheng: yes.

Interviewer: you put it back and let me have a look. His mouth is still open.

Wu Guozheng: because it thinks it is still dangerous, you see, it will come and bite me, and then get into the soil.

Interviewer: in this way, you can catch the tail.

Wu Guozheng: yes, so it won't bite. You see, no matter how you step on it, it won't bite.

Crocodile turtles seldom attack people actively in the water, and only when they get out of the water do they feel that there is no sense of security.

Wu Guozheng: it attacks people because it is afraid of it. in fact, when we say fierce, it is very ferocious when it attacks people. For me, the fiercer it is, the more ferocious it is, the better.

Reporter: the better. Is it possible that the higher the price, the higher the price?

Wu Guozheng: yes.

This is the largest crocodile turtle that Wu Guozheng caught in this pond.

Wu Guozheng: this should be 20 jin.

Interviewer: how long have you been raised like this?

Wu Guozheng: this has also been kept for three years.

Interviewer: how much can a size like this sell?

Wu Guozheng: if it weighs 20 jin, it's about 600 yuan each.

Interviewer: 600 yuan for a turtle?

Wu Guozheng: 500 to 600 yuan.

Interviewer: how many turtles like this are in the pool?

Wu Guozheng: there should be 1/3.

Interviewer: is there 1/3?

Wu Guozheng: yes, yes.

Crocodile turtles are mainly eaten as meat turtles and are in great demand in the market.

Wu Guozheng: the tortoise shell and that bone can make soup, then the meat can be sliced to rinse, and then the limbs and heels can be stewed, which can be made into one turtle and three dishes.

Crocodile turtles are only part of Wu Guozheng's wealth. In Wu Guozheng's farm, there are other species, such as yellow-throated turtles, yellow-edge closed-shell turtles, pearl turtles, and so on, with sales of more than 10 million yuan in 2014. Relying on these rare turtles, Wu Guozheng has also become a rich and capable person in the eyes of the people around him.
