After retiring, Wu electrician had no other hobbies, and he didn't like to raise cats, dogs, and birds, etc., and he thought that those pets were noisy, and finally developed a strong interest in fish farming, but this incident happened again, which made him feel a little excited.

Zhang Zi'an smiled slightly, seeing his thoughts, "You don't need to waste food because of choking, after all, electricity leakage is a small probability event." ”

"No, no, no matter how small the probability is, once it happens to you, it is the difference between 0 and 1. Wu electrician waved his hand, he was reluctant in his heart, but there was no way, once he was bitten by a snake, he was afraid of the well rope for ten years.

Although it is theoretically possible to turn off the heating rod before each contact with the water to ensure safety, it is inevitable that no one will be slackened after a long time, especially if he has children at home.

If he insists on raising marine fish, there will definitely be a lot of pressure from his wife, and even for the sake of family harmony, he will not plan to keep it.

"Actually, if you're really interested in raising marine fish, I have a solution. Zhang Zi'an wasted no time in proposing: "You can use a heating rod with a working voltage of 24 volts, even if the electricity leaks, it will not endanger personal safety." ”

"Ahh

The safe voltage of the human body is 36 volts, and the voltage below 36 volts is very safe, and if the working voltage is 24 volts, even if the electricity leaks will not cause the slightest danger to the human body.

"Why haven't you seen anything for sale?" he scanned the various heating rods on display on the counter, all of which were all 220 volts.

"Uh...... I don't have a 24-volt heating rod here, so I've never even heard of it. The boss was equally puzzled.

Zhang Zi'an smiled slyly: "If you want to buy a 24-volt heating rod, I can leave you an address, this is a high-end aquarium equipment imported from Germany, it is more expensive, but it can definitely guarantee safety, it depends on whether you are willing to invest in safety." ”

The audience in the live broadcast room suddenly scolded, and the manager of the store was going to take advantage of the fire to rob and take the opportunity to sell his own things......

Of course, Electrician Wu couldn't see the barrage, and thought that Zhang Zi'an was going to recommend other aquarium equipment stores.

When he was not retired, he had to participate in the safety production study organized by the factory every year, and he had seen and heard many tragic accidents caused by negligence, failure and misoperation, and knew that safety was priceless, and accidents always happened when people thought that accidents would not occur.

He immediately patted his chest and said, "How expensive can it be? Is my retirement salary enough for one month?"

Some people spent tens of thousands of dollars to buy SLR cameras and lenses and then walked the streets and alleys to take pictures, some people became obsessed with aerial photography, bought drones to drill into the ravine all day long, and then bought new ones after the crash...... Compared to these, the cost of fish farming is already very cheap.

As for my wife's nagging, I have been listening to it for decades, and my ears have a cocoon, so let her nag it.

"That's not going to work. Zhang Zi'an added Wu Electrician's WeChat and sent the address of his store.

Wu electrician glanced at the address, he led his grandson to sneak out of the house, today is no time to pass, after returning home, his wife will definitely be furious, he plans to stop for a few days and then go.

He said goodbye to Zhang Zi'an and Xiaoxue, and led his little grandson out of the fish market building.

The owner of this aquarium equipment was also very curious, and asked Zhang Zi'an where he got the heating rod with a working voltage of 24 volts, because he knew that the more high-end equipment was, the higher the profit, but Zhang Zi'an looked at him left and right, and casually found an excuse to leave the third floor with Xiaoxue and go down the stairs to the second floor.

On the second floor, there are fish tank landscaping supplies such as bottom sand, live stones, aquatic plants, seaweed, filter materials, coral reefs, and decorative corals.

Fish tank landscaping is a technical work, in addition to ingenuity, the most important thing is to have a pair of eyes that can find beauty. The same bottom sand, living rocks and corals, in the hands of some people can only play with mud, and in the hands of others can become a beautiful underwater dragon palace, not everyone has such talent and patience, many people prefer to spend money directly to buy the finished product.

If Zhang Zi'an browsed on the third floor, then on the second floor, he had to carefully observe and select qualified materials for building his own aquarium.

"Wow! It's like a garden! It's so beautiful!" Xiaoxue's eyes lit up and she couldn't help but admire.

Indeed, unlike the brightly lit third floor, the second floor is brightly dimmed, and the most prominent central area is all lined with finished landscape jars that each store is proud of, using colorful lights to enhance it, and the green of aquatic plants and seaweed creates a beautiful scenery.

There was a notice on the wall on the second floor prohibiting photography, and Xiaoxue said sorry to the audience in the live broadcast room and temporarily stuffed her phone into her pocket.

The audience complained again and again, and could only hear the sound, but the picture was black.

There is no shopping guide on the second floor to solicit guests, probably because it is too inefficient, because the customers on the first and third floors are rushing to buy fish and equipment, and the customers on the second floor often wander between different landscaping tanks for a long time, only admiring but not paying for them, or quietly taking pictures of the landscaping in the tank with their mobile phones, and planning to go home and cottage it.

Merchants are not in a hurry, and sit leisurely and play mobile games.

The landscaping tank is very profitable, and it will not be open for three years, and it will be open for three years.

It's okay, no one bother, customers can watch as much as they want, and watch as long as they want.

"Mr. Manager, why are the landscaping styles of these fish tanks different?" Xiaoxue was keenly aware of this after observing.

"Because these are different genres of landscaping. Zhang Zi'an pointed to a recent imaging tank and introduced, "You see, this tank uses a lot of sunken wood and rough rocks, the roots of the phoenix fern are attached to the sunken wood, the bottom sand is planted with water banyans, and the swimming fish with orange-red dorsal fins and shaped like Mohican hairstyles are West African short snappers, does the overall look feel very wild?"

Xiaoxue nodded, "Really, especially this West African short snapper, it looks quite funny." ”

"Fish tanks like this are West African-style landscaping, but it's not very orthodox, and orthodox West African-style landscaping should use black wood ferns, not anchovy ferns. Zhang Zi'an glanced at the merchant from a distance, "The phoenix fern grows fast and has strong vitality, and the merchant often uses it to replace the black wood fern, and the appearance is almost the same, and ordinary people can't tell the difference at all." ”

Xiaoxue stuck out her tongue, "No wonder netizens say that the water in the fish market is very deep, and even the small aquatic plants are shoddy!"

"It's not shoddy, the price of these two ferns is about the same, but the anchovy fern landscaping is more convenient, and the time to arrange the black wood fern in the fish tank is enough to arrange the anchovy fern in two fish tanks. Zhang Zi'an corrected.

"What about this? This one looks very quiet. Xiaoxue asked again, pointing to another landscaping tank.

The layout of this landscape tank is unusually simple, the mini dwarf pearl water plants cover the entire bottom of the tank, like a hill around the low middle slightly high, two long strips of rock are inverted eight diagonally inserted at the top of the hill, like a deserted tombstone, a few wisps of large sedge grass swaying with the water waves next to the rock, the white and blue lights create a clear sky atmosphere, looking at it has a very ethereal and lonely feeling, like standing in front of the hero's grave hanging.

"This is a typical Japanese landscaping, other styles are additional, but the Japanese style is subtraction, the fewer things in the tank the better, and the simpler the elements, the better. Zhang Zi'an said with a smile, "Anyone who has this kind of cold style guesses in the Japanese style, it's right." ”

The netizens in the live broadcast room were already anxious when they couldn't see the picture, and they were even more fried when they heard it.

"This is sexual harassment, right?

"The sexual harassment store manager knows that we can't see it, and he immediately reveals his ugliness......"
