"That is to say, as long as there are interfering devices, the signal transmission of these tiny devices will be blocked.
In addition, some sound-collecting equipment can play ultrasonic high-frequency background sounds to affect the audio monitoring of these sound-collecting 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: "As the saying goes, "the devil is as high as the road," drones and anti-drone technologies have actually been restricting each other, promoting each other, and growing with each other. Maybe the countermeasures I proposed
The control method will not take long to be overcome and applied to new drone equipment.
At that time, there will also be more advanced countermeasures."
After hearing Wu Hao's words, everyone agreed. Indeed, both drone technology and countermeasures are advancing rapidly. It is difficult to say whether these current countermeasures can cope with future drone technology.
.So relevant countermeasures and countermeasures technologies must be implemented quickly.
“In addition to the drone technologies and product equipment shown today, we also have a series of other related drone products. These products, equipment and technologies have also been unveiled and demonstrated at 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 said while looking at everyone.
Chang Shengjun and the others also smiled and nodded after hearing Wu Hao's words. Indeed, they all knew about those products and equipment technologies, so there was 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 dinner time without realizing it. If you don't mind, let's go to the company restaurant and have a casual meal together.
Chang Shengjun and the others laughed immediately after hearing this. Chang Shengjun smiled at Wu Hao and said, "I've heard for a long time that the food standard in your company's restaurant is comparable to that of pilots. We have to try it this time."
In arranging this meal, in addition to basic etiquette, Wu Hao also gave Chang Shengjun and the others a digestion time and a private communication time.
After all, after reading so many things, everyone must have a lot of words hidden in their hearts. There are some words that Wu Hao may not be able to say in front of so many people, so Wu Hao plans to invite everyone to have a casual meal and take a rest.
Let’s talk about the next thing in the afternoon.
He led Chang Shengjun and the others to the restaurant, and everyone immediately ordered something to eat. Wu Hao was naturally accompanying them. He shared a table with Chang Shengjun, Zeng Kecheng and Feng Kun, so they could chat while eating.
Have a chat.
In fact, sometimes, a lot of cooperation is achieved in this kind of private chat.
"This beef with soy sauce tastes good, very authentic." Chang Shengjun couldn't help but praise after eating a piece of beef with soy sauce.
"I remember the last time I had such authentic soy sauce beef was in 1993. At that time, I just started working and went on a business trip to northern Hebei. A local comrade took us there. It was a small shop.
, the shop is not big, only about ten square meters, and it is on the old street.
At that time, material conditions were scarce, so this soybean was considered a rare commodity, but even so, this small shop was overcrowded. It only sold it in the morning every day, and it was basically sold out around ten in the morning.
When we were led by local comrades, they had already sold out. In the end, it was the coordination of local comrades who evened out two kilograms for us.
Needless to say, the soy sauce beef was really authentic and left a deep impression on us. So from then on, basically every time we passed by there, we would go to this store to buy a few kilograms of soy sauce beef.
The sauced beef from this restaurant has also become very popular in our system, and it has become a souvenir for everyone to take with them when visiting friends. For this reason, we have also thought about it and thought about inviting the owner of this restaurant to our office canteen.
It specializes in making soy beef, but the boss was already over 60 at that time, and they refused to move the place.
We also thought about asking the boss for the recipe, but he was unwilling to disclose it and said he wanted to leave it to his grandson."
What happened next? Wu Hao took a bite of the food and asked immediately.
Hearing his inquiry, Chang Shengjun sighed and said: "After the new millennium, the boss got 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 on, the old man's other sons and daughters were jealous and wanted to get involved, so the store went downhill more and more.
Later, the old man suffered a stroke because of the anger of his sons, and finally passed away. Due to the competition between his sons and daughters, the business of this store became worse and worse, and eventually it closed down."
I didn't expect such a thing to happen. This is also in line with the sentence, everything will be prosperous for the family. Feng Kun said with emotion.
After hearing Feng Kun's words, everyone nodded.
Chang Shengjun, on the other hand, sighed and said: "Actually, even if they manage it well, this store can't continue to operate. Because the old man braises the beef in soy sauce by dismantling the hot pot and slow-cooking and soaking it in one pot.
Buying for one day is too time-consuming and labor-intensive, and the cost is high. After the new millennium, people began to pursue high-quality and low-priced fast-moving consumer goods, and these stores that adhere to traditional craftsmanship will naturally have no market."
Chang Shengjun's words immediately resonated with everyone. It was indeed the case. There were indeed many good things in the past, but because they were made by hand, they were time-consuming, labor-intensive, and costly. They were eventually replaced by new technology and machines. The old things
It will also die.
It’s not that old things are bad, old things are very good, but they just don’t adapt to the rules of market development, so they are eliminated.
This is just like the sweet potato vermicelli that many people like to eat. In the past, all sweet potato vermicelli were made by hand, so they were more chewy and delicious. But now, in order to increase sales, the sweet potato vermicelli is produced by machines.
Machine-made vermicelli has a large output and is easy to produce, so it has gradually become the mainstream of the market. Handmade sweet potato vermicelli has gradually disappeared, and only some rural areas still retain it.
However, with the continuous improvement of people's demand for material quality of life, this kind of handmade sweet potato vermicelli has begun to be popular among consumers again. However, because the output is too low, the price is several times that of machine sweet potato vermicelli. This has also led to many machine-made sweet potato vermicelli.
Vermicelli likes to be sold as fake handmade vermicelli. This has led to the phenomenon that most of the handmade vermicelli on the market are fake and genuine ones are hard to find.
