The earliest tram in China was put into use in Tianjin in 1900.

At that time, the literacy rate of the people in Tianjin was no better than that of Datang, so at that time, numbers were not used to distinguish lines, but colors were used to distinguish them.

Red, yellow, blue, green, white, flower and purple, seven tram lines run through the main busy sections of Tianjin.

As for the so and so road used by later generations, it actually comes from Britain and is translated from English route, which means "path".

In the face of the doubts of Cui Luo and Lu Dejing, Li forgets to worry. He can only spare his head. He puts forward it painfully and uses color to distinguish the bus routes.

This makes Cui Luo and Lu Dejing applaud. People can't read, and color is the most convenient way to distinguish.

After discussion, the three people arranged three horizontal and three vertical lines in the Chang'an city of Nuo University, plus a circular route from the west city to the east city. There are seven operation routes of public carriages, which can correspond to the seven colors of red, yellow, blue, green, white, black and purple.

After the matter was discussed properly, Cui Luo and Lu Dejing were responsible for arranging yamen servants to paste notices in each lane to inform the people that the public carriage was about to be put into operation and the route map of the seven operation lines.

This matter immediately became the hottest topic in Chang'an city. Everyone met and discussed the public carriage.

"Dalang, have you heard? Huxianbo has made a new thing again."

"You know, you're talking about the public carriage? Hey, this is a new thing. The county government said that you can take a carriage for two Wen? Is there such a good thing? Huxianbo is afraid to die?"

"Who knows? Anyway, huxianbo doesn't need copper money and can afford it. If this is true, I have to thank huxianbo. It's good for us."

"Isn't that right? My mother has always wanted to go to the xuandu temple to burn incense. My son is unfilial. I can't borrow a carriage and my legs are inconvenient. If the public carriage is true, it's the blessing of the Taoist ancestors. I can take my mother to the xuandu temple."

"Wait, the Yamen can say. In five days, the public carriage will be put into use. I asked clearly. The blue carriage will pass through qixiamen street in front of our Lifang, go to jinguangmen street, change the red carriage, and you can go directly to the east or west market. It's very convenient to buy things."

In fact, compared with the price of the ox cart with a load of 100 kg and a distance of 100 miles in Datang, the fare of the public carriage with two Wen is not cheap. But the ox cart started fifty Wen. It collected so much no matter it was less than fifty miles. In this way, two Wen can take a carriage, which is much cheaper.

When the average monthly income of the people in Chang'an is consistent, the fare of two Wen is not low consumption, but the enthusiasm and expectation of the people for the public carriage are not reduced at all.

Li Qieyou was busy getting the farmers in Dingzhou village familiar with the driving route, carrying out pre job training, arranging people to buy horses and adjust public carriages... After a series of things, the ten days passed in a flash.

This morning, just after the morning drum of Chang'an city was knocked, the square door was opened. The pawn guarding the square door saw many people pouring out of the square door and standing on the street outside the square looking around.

"Did you come? Did you come? Did you see it?"

"Isn't it so early? The door of the workshop has just been opened. Wait a minute. The announcement is sure to say today?"

"Yes, today."

The old pawn was surprised and asked, "gentlemen, what are you waiting for?"

"Wait for the coach."

"Dare you ask what the coach is?" the old soldier continued to ask.

His words made all the people around him laugh and say, "this military master, but he's not in Chang'an city these days?"

The old soldier nodded: "I asked for leave a few days ago and went back to my hometown for funeral. I only returned to Chang'an city yesterday."

"No wonder Junye didn't know about it. This public carriage is a new thing made by Huxian Bo. It's the carriage carrying passengers. It runs along seven fixed lines in Chang'an city. If you need to take a bus, you can reach out and stop the carriage. You can get off at any time when you arrive at your destination, and the fare is only two Wen at a time." the people in the workshop immediately explained enthusiastically.

The old pawn was surprised and said, "are there such good things? The Huxian uncle really has too much gold in the house to spend? After a certain value, I'll try it."

"Ha ha, everyone thinks so. Don't you think they're all waiting for the bus?"

All the people looked forward to it. Suddenly someone shouted, "come, come! The green carriage is the public carriage passing through our lane. I saw the cover on the carriage!"

Following the direction of his finger, the people looked up and saw that it was a four-wheel carriage driving slowly. The carriage of the carriage is higher than the ordinary carriage, and there is a green cover above it.

There were also four large characters in white on the cover, "public carriage". This is naturally Li Er's handwriting, which was shamelessly used by Li Qieyou to print into a cover for a public carriage.

They quickly waved their arms and motioned to get on the bus.

But the carriage didn't stop. When it slowly passed in front of the people, the driver reluctantly left a sentence: "sorry, everyone, the car is full. Wait for the next trip."

His words naturally caused an uproar among the people, and then quickly turned around and ran in the direction of the carriage.

There are only about a dozen people in this public carriage. There are not less than a hundred people waiting for a taste of fresh food in front of them. When will they go?

What's more, there are other lanes in front of them. Just run two steps and stop the carriage in the front lane.

Those people who managed to stop the public carriage excitedly held up two Wen and asked the Yu Fu, "is it two Wen? I'll go to Xishi!"

The farmer in Dingzhou village smiled and nodded: "yes, two Wen. Just throw it directly into this box."

At the entrance of each carriage, there was a huge locked box with a slot for coin. This is the money collection box made by Li forget worry, which is directly in place in one step, "no ticket sales".

The people threw two Kaiyuan Tongbao and boarded the carriage.

Even if there are no seats, they can only stand in the middle of the carriage and enjoy it. Whether they knew each other or not, they talked excitedly and talked about the novelty of the public carriage.

The public carriage became popular on the first day of its operation in Chang'an city.

Carpenter Liu led his three sons and a group of apprentices. He worked overtime for ten days, but he only built more than 50 carriages.

There are seven routes in Chang'an city. On average, each route can only be allocated to seven or eight carriages. Even if it is full, it can only transport 500 or 600 people at a time.

Chang'an City has a population of one million, and even if it is calculated by one percent, it is also a population of 10000. These more than 50 carriages are just a drop in the bucket.

The more than 50 farmers in Dingzhou village hardly had a rest from morning to night. Until the evening drum sounded and the carriage stopped operating, they found that they had not even eaten in a day.

Everyone was so hungry that his chest was close to his back, but his heart was very excited.

When they drove the carriage back to Dingzhou village, they opened the money box and counted it, which startled everyone.

In almost every carriage's money box, there was no less than consistent copper money. There were more than 50 carriages. The last statistics showed that the income of the day was about 60.

Even Li forgot to worry about this income, which is more than twice as high as he expected before
