However, Duan Yun asked Gao Lei to go to Guangzhou to find these chips this time, and he didn't have much hope, but if he could really find any special chip purchase channels, it would undoubtedly be of great significance to Duan Yun.

This time, Duan Yun asked Gao Lei to look for chips, in addition to NE555 and Microsoft 8088, there are also 6502 microprocessors and 741 operational amplifiers of Feiji Semiconductor Company.

These chips are all successfully developed in the sixties and seventies, among which the 741 operational amplifier can be used to make audio and video preamplifiers, voltage comparators, and other electronic systems, which are part of the common daily electronic products in later generations.

Although many of these chips have begun to enter the brink of elimination in the world in this year, but in China, there is no doubt that they are very advanced, such as 6502 microprocessor, this chip is a product developed by the United States in 1975, widely used in Nintendo games in the 80s, after the release of FC in 1983, such as "Pinball", "Donkey Kong", "F1 Car", "Balloon Wars" and "Locomotive Competition" and other classic games were born.

In China, at the end of the last century, the FC compatible machines/Xiaobawang learning machines that were popular all over the country and Wenqu Xing, which almost everyone had one, all used 6502 CPUs. Xiaobawang mostly uses UA6527 produced by Taiwan's UMC, and it can be said that this CPU has accompanied the childhood and youth of China's post-80s and post-90s.

"Okay, it's on me!" Gao Lei happily agreed.

"What's more, your electronic watch business may become more and more difficult to make money in the future, and you have to find a new way to make money in advance. Duan Yun said.

"What you said makes sense, a few days ago when I was selling watches in 616, I met several peers, they all pushed each other's prices very low, and there were people in other factories who sold them, and they couldn't sell a few dollars a day without lowering the price...... Gao Lei frowned, and then said: "But now I feel that this electronic watch is quite profitable, and I can't find other things that make money quickly......"

"Have you been watching TV lately?" Duan Yun asked.

"Look, "Blood Suspicion" has been very popular recently, and I go to the Stadium of Lights every night to watch it...... Hey, why do you say that RB woman is so beautiful, those thighs are really white......" Gao Lei said excitedly.

"I suggest you take a look at Gaodi Street in Guangzhou, if there is a TV series starring in the same style of 'Sachiko shirt' or 'Guangfu shirt', that is to buy more and bring it back to Daxing, it will definitely sell well. Duan Yun said.

In the TV series "Blood Suspicion", in addition to the mess of the protagonists, what also became popular was the clothes worn by the protagonists in the play. At that time, the popular "Sachiko shirt", "Mitsuo shirt" and "Oshima Shigeru bag" also made a lot of money for the merchants at that time.

What's more, the hairstyle of "Sachiko Oshima" in the play was imitated by the girls. In today's terms, "Sachiko shirt" became a hot topic back then.

As for the Guangzhou Gaodi Street mentioned by Duan Yun, it is a famous clothing street in Guangzhou.

In the late 70s and early 80s of the last century, the original Gaudy Street was not only a world of clothes, but also small hardware, wool, leather goods, electronic watches, calculators and so on.

By 1 October 1980, the Industrial and Commercial Bureau was established and licensed vendors operating on Gaudy Street.

Gaodi Street became the first industrial market in Guangzhou and even in the country, and since then Gaodi Street has become one of the most famous and largest clothing wholesale and retail markets in China.

"Gaudy Street...... I remembered. Gao Lei nodded when he heard this, and then asked curiously: "Hey, I said how do you know that there is still this place in Guangzhou?"

"A friend I know who often goes to Guangzhou to resell clothes and told me about some things in Guangzhou. Duan Yun prevaricated casually.

"That's right. ”

"By the way, when are you going to leave?" Duan Yun asked.

"I'm going to leave the day after tomorrow. ”

"You'd better buy a ticket to Guangzhou right away today. Duan Yun pondered for a moment, and then said: "You have a lot of things to buy in Guangzhou this time, it will be more and more difficult to ship electronic watches in the future, and the Sachiko shirt is about to go on the market, you are likely to not be able to grab the goods if you go late, and the opportunity to make money is actually fleeting, if you are slow, you can only drink soup......

"Makes sense. Gao Lei nodded when he heard this, and after thinking for a while, he said to Duan Yun: "Then I'll go to the train station to buy a ticket now." ”

"Is the money you brought this time enough, do you need me to lend you some more?" Duan Yun asked.

"No, I have a lot of money now. Gao Lei said, stood up and said to Duan Yun: "You're right, I can't rest now, if I can't make the money I should earn, I will always feel uncomfortable." ”

"You're right to think so, after making a lot of money and becoming a 10,000 yuan household, it's not a casual thing to eat and play whatever you want. Duan Yun said with a smile.

Seeing Gao Lei's attitude, Duan Yun's heart suddenly relaxed.

Gao Lei can put all his mind on making money, so he will not easily make trouble for nothing, as his friend, Duan Yun naturally hopes that he can live a good life in the future.

In addition, Gao Lei has done a small business before, and he has some experience in business, and if he runs all over the country in the future, he can help Duan Yun do a lot of things.

"Okay, you're busy!" Gao Lei finished speaking, put on his sunglasses, and turned around and left the house.

"Wait!" Seeing that Gao Lei was leaving, Duan Yun suddenly stopped him.

"What else is going on?" Gao Lei was stunned when he heard this.

"Dongzi, don't work yet, ride your nephew and take Gao Lei to the train station. Duan Yun said.

Duan Yun hopes that Gao Lei will leave as soon as possible, after all, he is now looking forward to Gao Lei helping him find a channel to buy chips as soon as possible.

"Hmm. Cao Dong answered, and then sat down at the door and parked the nephew, took the key and unscrewed the switch.

"This car is so bullish, I saw it just now, I didn't expect it to be yours?" Gao Lei looked surprised, and then asked: "How much money is this to buy?"

"These are all old cars that have been eliminated by the Public Security Bureau, and I bought them from a friend. Duan Yun said with a smile.

"Then can you contact that friend of yours, I want to buy one too. Gao Lei touched the shell of his nephew with his hand, his eyes were full of fire, he obviously liked this kind of motorcycle very much.

"I'm afraid this is a bit difficult, now there are very few second-hand cars that have been eliminated, the person I know is from the Mining Bureau, this car I exchanged with him with a speaker, and the friendship is average, I don't know if he will come in the future......" Duan Yun frowned slightly and said.

"That's ......," Gao Lei heard this, and a look of disappointment flashed on his face.

"But at present, I have two nephews here, if you can find the chip sales channel on the list I gave you this time in Guangzhou, I can give you one!" Duan Yun raised his eyebrows and said.

"That's great!" Gao Lei suddenly became excited when he heard this, and said to Duan Yun: "Don't worry, even if I go through the whole of Guangzhou this time, I will help you find these chips!"
