"In other words, as long as there is an interfering device, the signal transmission of these tiny devices will be blocked.

In addition, some sound receiving equipment can completely play ultrasonic high-frequency background sound to affect the audio monitoring of these receiving microphone arrays.

In addition, the battery life of these tiny devices is very limited, so blocking the venue in advance, or delaying the meeting, will effectively prevent these tiny devices from monitoring and stealing information. "

Speaking of this, Wu Hao said with a smile: "The so-called Tao is one foot high and the devil is one foot high. In fact, drones and anti-drone technologies have always restricted each other, promoted each other, and increased each other. Maybe the countermeasures I raised It will not take long to overcome the means of control, and it will be used in new drone equipment.

At that time, more advanced countermeasures will also exist. "

Hearing Wu Hao's words, everyone thought the same. Indeed, both drone technology and countermeasures are advancing rapidly. Whether these countermeasures can cope with future drone technology is hard to say. Therefore, relevant countermeasures and countermeasures must be stepped up.

"In addition to the UAV technology and product equipment shown by you today, we also have a series of other related UAV products. These product equipment and technologies have also been unveiled and demonstrated in various domestic exhibitions. I won't take up your time to introduce too much here.

If you want to know more, you can consult our staff later, and they will give you more detailed answers. "Wu Hao looked at the crowd and said.

Chang Shengjun and the others also smiled and nodded after hearing Wu Hao's words. Indeed, they already know about those products and equipment technologies, so there is no need for Wu Hao to waste time introducing them again.

Looking at the time, Wu Hao said to Chang Shengjun and the others: "Director Chang, it's already past the meal time. If you don't mind, let's go to the company restaurant to have a casual meal together.

Chang Shengjun and the others immediately laughed when they heard the words. Chang Shengjun smiled at Wu Hao and said, "I've heard that the food standard in your company's restaurant is comparable to that of a pilot. This time we have to try it out."

Apart from the basic etiquette in arranging this meal, it was actually Wu Hao giving Chang Shengjun and the others a time to digest and communicate in private.

After all, after seeing so many things, everyone must have a lot of things hidden in their hearts. Some words may not be able to be said in front of so many people in front of Wu Hao, so Wu Hao plans to invite everyone to have a light meal, then take a rest, and talk about the next thing in the afternoon.

Leading Chang Shengjun and the others to the restaurant, everyone ordered something and started eating. Naturally, Wu Hao also accompanied them here. He shared a table with Chang Shengjun, Zeng Kecheng and Feng Kun, so they could chat while eating.

In fact, sometimes, a lot of cooperation is reached in this kind of private chat.

"This sauced beef tastes good, very authentic." Chang Shengjun couldn't help but praise after eating a piece of sauced beef.

"I remember that the last time I ate such authentic sauced beef was in 1993. At that time, I just started working and went on a business trip to northern Hebei. At that time, a local comrade took us there. It was a small shop. , the shop is not big, about ten square meters, on the old street.

At that time, the material conditions were expensive, and this sauced beef was considered a rare commodity, but even so, the small shop was overcrowded. His family only sold it in the morning every day, and it was basically sold out by around ten o'clock in the morning.

When we were led by the local comrades, they were already sold out. In the end, it was the coordination of the local comrades that gave us two catties.

Needless to say, the sauced beef is really authentic and left a deep impression on us. So since then, basically every time we pass by there, we will go to this store to buy a few catties of sauced beef.

The sauced beef of this restaurant has also become popular in our system, and it has become a souvenir for everyone to take along to visit friends on the street. For this reason, we thought about inviting the owner of the shop to make sauced beef in our canteen, but the owner was already in his sixties at that time, and he refused to move the place.

We also thought about asking the boss for the recipe, but he didn't want to disclose it, saying it was for his grandson. "

Then, after Wu Hao took a bite of the food, he immediately asked.

Hearing his question, Chang Shengjun sighed and said: "After the new millennium, the boss is getting older, and his son was laid off from the factory, so he came to the store to take over.

The business was good at the beginning, but later, because the other sons and daughters of the old man were jealous, they wanted to get involved, so the store went downhill more and more.

Later, the old man suffered a stroke due to the anger of his sons, and finally passed away. Under the competition of several sons and daughters, the business of this store became worse and worse, and finally closed down. "

I didn't expect such a thing to come out, and this is also in response to the sentence, family and everything are prosperous. Feng Kun said with emotion.

Hearing Feng Kun's words, everyone nodded.

As for Chang Shengjun, he sighed and said: "Actually, even if they manage well, this store can't continue to operate. Because the old man uses the stewed beef in a hot pot to cook and soak slowly, UU reading www .uukanshu.com It takes a day to buy a pot of stew. This is too time-consuming and labor-intensive, and the cost is high. After the new millennium, people began to pursue high-quality and cheap fast-moving consumer goods, and these stores that insisted on traditional craftsmanship naturally lost their market. "

Chang Shengjun's words immediately resonated with everyone, and it was true. There were indeed many good things in the past, but because of the time-consuming, labor-intensive, and high cost of hand-made, they were eventually replaced by new technology and machines, and the old things died out.

It's not that old things are bad, but old things are very good, but they don't adapt to the rules of market development, so they are eliminated.

This is like the sweet potato vermicelli that many people like to eat. The previous sweet potato vermicelli is all handmade, so it is more delicious. In order to increase sales, the current sweet potato vermicelli is produced by machine. Machine-made vermicelli has a large output and is easy to produce, so it has gradually become the mainstream of the market, and handmade sweet potato vermicelli has gradually disappeared, and only some rural areas still have reservations.

However, with the continuous improvement of people's demand for material quality of life, this kind of handmade sweet potato vermicelli has become popular with consumers again. However, because the output is too low, the price is several times that of machine sweet potato vermicelli. This has also caused many machine-made sweet potato vermicelli to be sold as counterfeit handmade vermicelli. This has led to the phenomenon that most of the handmade vermicelli on the market are fake, and real products are hard to find.
