After the hot-air balloon passed by Qingzhou City, there was a heated discussion about what it was.

But the next day's newspaper completely let the people understand what this is, and the term hot air balloon has become a popular and fashionable term in Qingzhou.

"What's this balloon?" Asked a businessman who had just entered the city.

"This balloon is something flying in the sky. It's like a ball." A native of Qingzhou answered with pride.

"The flying ball?" the stranger merchant was puzzled.

"Of course, even pigs can fly in Qingzhou. Everything can happen in Qingzhou, which is said in the newspaper." Qingzhou people have strong self-confidence.

The merchant laughed awkwardly. In his opinion, all the people in Qingzhou are ill, and they are very ill.

He heard people discuss this question many times along the way, but everyone's answer was different, which made him more confused.

While he was wondering, he saw a crowd of people suddenly exclaim and look up to heaven.

He followed, and his jaw fell down.

I saw a huge sphere floating slowly in the sky. A huge banner was pasted on the balloon, and three vertical banners were also hung on the hanging basket.

banner reads: Qingzhou chamber of Commerce sells mirrors, perfume, drunk Qingzhou liquor, wants to buy as soon as possible, chamber of Commerce address... "

The huge hot-air balloon didn't fly high and was very conspicuous. When they saw the balloon, they also saw the advertisement on it.

The merchants from other places were stunned. He came here with admiration. Is this Qingzhou where businessmen flock to? It's really an extraordinary place.

The people in Qingzhou were also shocked. They didn't expect that the balloon could still be used like this.

Those merchants who were living in Qingzhou were all human beings, and they understood what they had learned in an instant.

In the next few days, people in Qingzhou gradually became familiar with the hot air balloons floating in the sky.

Every time the balloon flies by, even the children in the city will run with it, very happy.

at the same time, the colorful eyeliner in the city of Qingzhou also passed back the strange news of hot air balloon, and collected all aspects of the balloon.

However, Li San is free to deal with these matters, while Xiao Ming is busy dealing with businessmen. After all, he is still the president of Qingzhou chamber of Commerce.

"Your Highness, this balloon is really wonderful. I don't know if your highness can also put the name of Cao family's Bank on it and write down the business of Cao family's Bank."

It was the first time that Cao Zhengyang found Prince Qi's residence.

He went to the chamber of Commerce first. When he learned that the chamber of Commerce had no right to interfere, he immediately came to king Qi's house to visit Xiao Ming.

Li Kaiyuan didn't understand the advertisement. Naturally, Xiao Ming didn't trust to give it to him.

Xiao Ming ordered Lin Wentao to do the job of advertising on the balloon. In the era of closed information, it is very difficult to publicize their own shops, especially many merchants set up their workshops outside Qingzhou City.

After Xiao Ming changed hands on SOAP technology, there are no less than 50 soap shops outside Qingzhou City.

All of these 50 companies want to sell more soap. At this time, the effect of advertising will be important. Whoever seizes the opportunity will gain the initiative and will get more profits.

"This..." In business, Xiao Ming naturally wants to raise the price. He hesitates and says: "it costs a lot to fly a hot-air balloon, which..."

Cao Zhengyang had been prepared for this. He said, "Your Highness, although you can say it directly, Cao will not let your highness spend money."

"In this case, Wang said that the thing hanging on the balloon is called advertisement. As the name suggests, it is advertised. Now that you need the advertisement, the cost of the advertisement is very different."

"Your Highness, please."

Xiao Ming continued: "you must have seen a lot of banners hanging on the balloon, and the positions of the banners are different. Then the problem comes. If the positions of each banner are different, the prices will be different. If the sizes of the banners are different, the prices will be different. So what position and how big banners do you need?"

Cao Zhengyang recalled that the banners on the balloon were really different in size and location.

He said with a smile: "Your Highness, why do you have to be so troublesome

Xiao Ming sneered in his heart, saying that you sent it to your door by yourself. The ten meter diameter balloon plus the position of the hanging basket, there are 30 advertising spaces for a balloon.

He said: "in fact, there are not many hot air balloons. They travel around the city once every ten days, three times a month. You must know that as long as the hot air balloon appears, it will cause people and merchants to watch."

Cao Zhengyang nodded.

"So if you contract it all three times a month, you'll have to pay 50000 taels of silver."

Cao Zhengyang almost said, "you robbed the money." In response, he immediately fell into silence.

Xiao Ming knew that would be the case. He analyzed it and said, "there are 30 advertising spaces on each hot air balloon, three times a month, which means that each advertising space is only about 600 taels of silver. The price is not expensive. The worst advertising space is only about 300 taels of silver three times a month."Cao Zhengyang nodded. It's really not expensive to return the advertising space.

But Haikou has already boasted, and Cao's Bank is about to open. He gritted his teeth and said, "Your Highness, fifty thousand is fifty thousand. This is the bank note of our Cao's Bank. You can exchange silver at any time with silver."

Xiao Ming took the bank note from Cao Zhengyang and felt comfortable, but also in a trance. He felt deeply about the financial strength of the Cao family.

This banknote is basically equivalent to modern paper money.

The fact that the Cao family was able to make merchants use the Cao family's banknotes in Dayu shows the strong strength of the Cao family's Bank.

But he doesn't worry. It won't take long for him to issue his own currency, but he has to reserve a lot of gold and silver before issuing it.

This gold and silver can only be obtained through foreign trade and plunder.

He clearly remembered the location of gold and silver mines in his mind, but he had to defeat the local western colonists before he could get them.

After seeing off Cao Zhengyang, Xiao Ming met with other merchants and introduced them to this kind of advertisement. The merchants generally accepted the advertisement very quickly.

However, Cao Zhengyang is rich and powerful, and has contracted the advertisement for three months.

Busy in the afternoon, the businessmen who came to visit left one after another. At this time, Xiao Ming took the money to Bowen college.

He has fulfilled his promise. All the advertising revenue will be used for the education of Bowen college, whether it is the purchase of experimental materials, the improvement of students' living standards, or the purchase of special uniforms for students.
